The quantum energy of the photon radiated by a body with de Broglie wavelength, as it moves with velocity v, can be defined within relativistic physics by rest energy E₀. In this way, we can show the connection between the quantum of radiation energy of the body and the rest of energy E₀ and thus combine what has been incompatible so far, namely relativistic and quantum physics. So, here we discuss the unification of relativistic and quantum physics by introducing the factor k that is analog to the Lorentz factor in Einstein's theory of relativity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=de%20Brogli%20wavelength" title="de Brogli wavelength">de Brogli wavelength</a>, <a href="https://publications.waset.org/abstracts/search?q=relativistic%20physics" title=" relativistic physics"> relativistic physics</a>, <a href="https://publications.waset.org/abstracts/search?q=rest%20energy" title=" rest energy"> rest energy</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20physics" title=" quantum physics"> quantum physics</a> </p> <a href="https://publications.waset.org/abstracts/135170/de-broglie-wavelength-defined-by-the-rest-energy-e0-and-its-velocity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135170.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">156</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14784</span> Relativistic Energy Analysis for Some q Deformed Shape Invariant Potentials in D Dimensions Using SUSYQM Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Suparmi">A.

Within a self-similar model for the hydrodynamic multi-fluid equations, we investigated the expansion of dense plasma. The weakly relativistic electrons are produced by ultra-intense laser pulses, while ions are supposed to be in a non-relativistic regime. It is shown that dense plasma expansion is found to be governed mainly by quantum contributions in the fluid equations that originate from the degenerate pressure in addition to the nonlinear contributions from exchange and correlation potentials.

Our dynamical model includes Newtonian perturbations of eight planets, the Moon, the Sun and three massive asteroid (1Ceres, 2Palas and 4Vesta). We showed the variation in orbital elements of nominal orbit of the asteroid. In the presence of Yarkovsky effect, the Semi-major axis of the orbit of the asteroid is decreases by 350 m over one period of orbital motion. The magnitude of Yarkovsky force is computed. We find that maximum magnitude of Yarkovsky force is 0.09 N at the perihelion .

In regions with huge electric field strength, RREA can multiply via relativistic feedback. The relativistic feedback is caused both by positron production and by runaway electron bremsstrahlung gamma-rays reversal. In complex multilayer thunderstorm electric field structures, an additional reactor feedback mechanism appears due to gamma-ray exchange between separate strong electric field regions with different electric field directions. The study of this reactor mechanism in conjunction with the relativistic feedback with Monte Carlo simulations or by direct solution of the kinetic Boltzmann equation requires a significant amount of computational time. In this work, a theoretical approach to study feedback mechanisms in RREA physics is developed. It is based on the matrix of feedback operators construction. With the feedback matrix, the problem of the dynamics of avalanches in complex electric structures is reduced to the problem of finding eigenvectors and eigenvalues. A method of matrix elements calculation is proposed. The proposed concept was used to study the dynamics of RREAs in multilayer thunderclouds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=terrestrial%20Gamma-ray%20flashes" title="terrestrial Gamma-ray flashes">terrestrial Gamma-ray flashes</a>, <a href="https://publications.waset.org/abstracts/search?q=thunderstorm%20ground%20enhancement" title=" thunderstorm ground enhancement"> thunderstorm ground enhancement</a>, <a href="https://publications.waset.org/abstracts/search?q=relativistic%20runaway%20electron%20avalanches" title=" relativistic runaway electron avalanches"> relativistic runaway electron avalanches</a>, <a href="https://publications.waset.org/abstracts/search?q=gamma-rays" title=" gamma-rays"> gamma-rays</a>, <a href="https://publications.waset.org/abstracts/search?q=high-energy%20atmospheric%20physics" title=" high-energy atmospheric physics"> high-energy atmospheric physics</a>, <a href="https://publications.waset.org/abstracts/search?q=TGF" title=" TGF"> TGF</a>, <a href="https://publications.waset.org/abstracts/search?q=TGE" title=" TGE"> TGE</a>, <a href="https://publications.waset.org/abstracts/search?q=thunderstorm" title=" thunderstorm"> thunderstorm</a>, <a href="https://publications.waset.org/abstracts/search?q=relativistic%20feedback" title=" relativistic feedback"> relativistic feedback</a>, <a href="https://publications.waset.org/abstracts/search?q=reactor%20feedback" title=" reactor feedback"> reactor feedback</a>, <a href="https://publications.waset.org/abstracts/search?q=reactor%20model" title=" reactor model"> reactor model</a> </p> <a href="https://publications.waset.org/abstracts/142458/feedback-matrix-approach-for-relativistic-runaway-electron-avalanches-dynamics-in-complex-electric-field-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142458.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">172</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14778</span> Generalized Dirac oscillators Associated to Non-Hermitian Quantum Mechanical Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Debjit%20Dutta">Debjit Dutta</a>, <a href="https://publications.waset.org/abstracts/search?q=P.%20Roy"> P.

We can observe interesting fact that for such systems a class of potentials, namely the PT symmetric and η-pseudo Hermitian admit real eigenvalues despite being non Hermitian and analogues of those system have been experimentally verified. Point to be noted that relativistic non Hermitian (PT symmetric) interactions can be realized in optical structures and also there exists photonic realization of the (1 + 1) dimensional Dirac oscillator. We have thoroughly studied generalized Dirac oscillators with non Hermitian interactions in (1 + 1) dimensions. To be more specific, we have examined η pseudo Hermitian interactions within the framework of generalized Dirac oscillator in (1 + 1) dimensions. In particular, we have obtained a class of interactions which are η-pseudo Hermitian and the metric operator η could have been also found explicitly. It is possible to have exact solutions of the generalized Dirac oscillator for some choices of the interactions. Subsequently we have employed the mapping between the generalized Dirac oscillator and the Jaynes Cummings (JC) model by spin flip to obtain a class of exactly solvable non Hermitian JC as well as anti Jaynes Cummings (AJC) type models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dirac%20oscillator" title="Dirac oscillator">Dirac oscillator</a>, <a href="https://publications.waset.org/abstracts/search?q=non-Hermitian%20quantum%20system" title=" non-Hermitian quantum system"> non-Hermitian quantum system</a>, <a href="https://publications.waset.org/abstracts/search?q=Hermitian" title=" Hermitian"> Hermitian</a>, <a href="https://publications.waset.org/abstracts/search?q=relativistic" title=" relativistic "> relativistic </a> </p> <a href="https://publications.waset.org/abstracts/4071/generalized-dirac-oscillators-associated-to-non-hermitian-quantum-mechanical-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4071.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">458</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14777</span> Gravitationally Confined Relativistic Neutrinos and Mathematical Modeling of the Structure of Pions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Constantinos%20Vayenas">Constantinos Vayenas</a>, <a href="https://publications.waset.org/abstracts/search?q=Athanasios%20Fokas"> Athanasios Fokas</a>, <a href="https://publications.waset.org/abstracts/search?q=Dimitrios%20Grigoriou"> Dimitrios Grigoriou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We use special relativity to compute the inertial and thus gravitational mass of relativistic electron and muon neutrinos, and we find that, for neutrino kinetic energies above 150 MeV/c2, these masses are in the Planck mass range.

These models contain no adjustable parameters and by comparing their predictions with the experimental values of the masses of protons and pions, we compute a mass of 0.0437 eV/c2 for the heaviest electron neutrino mass and of 1.1 x10-3 eV/c2 for the heaviest muon neutrino mass. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=geons" title="geons">geons</a>, <a href="https://publications.waset.org/abstracts/search?q=gravitational%20confinement" title=" gravitational confinement"> gravitational confinement</a>, <a href="https://publications.waset.org/abstracts/search?q=neutrino%20masses" title=" neutrino masses"> neutrino masses</a>, <a href="https://publications.waset.org/abstracts/search?q=special%20relativity" title=" special relativity"> special relativity</a> </p> <a href="https://publications.waset.org/abstracts/67291/gravitationally-confined-relativistic-neutrinos-and-mathematical-modeling-of-the-structure-of-pions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67291.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">263</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14776</span> Relativistic Effects of Rotation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yin%20Rui">Yin Rui</a>, <a href="https://publications.waset.org/abstracts/search?q=Yin%20Ming"> Yin Ming</a>, <a href="https://publications.waset.org/abstracts/search?q=Wang%20Yang"> Wang Yang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For a rotational reference frame of the theory of special relativity, the critical radius is defined as the distance from the axis to the point where the tangential velocity is equal to the speed of light, and the critical cylinder as the set of all points separated from the axis by this critical radius. Based on these terms, two relativistic effects of rotation are discovered: (i) the tangential velocity in the region of Outside Critical Cylinder (OCC) is not superluminal due to the existence of space-time exchange; (ii) some of the physical quantities of the rotational body have an opposite mathematic sign at OCC versus those at Inside Critical Cylinder (ICC), which is termed as the Critical Cylindrical Effect (CCE). The laboratory experiments demonstrate that the repulsive force exerted on an anion by electrons will change to an attractive force by the electrons in precession while the anion is at OCC of the precession. Thirty-six screenshots from four experimental videos are provided. Theoretical proofs for both space-time exchange and CCE are then presented.

We adopted a relativistic approach using DFT theorem with local spin density approximation (LSDA). The electronic structure is performed within the framework of the Spin-Polarized Relativistic (SPR) Linear Muffin-Tin Orbitals (LMTO) with the Atomic Sphere Approximation (ASA) method. During the variational principle, the crystal wave function is expressed as a linear combination of the Bloch sums of the so-called relativistic muffin-tin orbitals centered on the atomic sites. The crystalline structure is calculated after an atomic relaxation process using the optimization of the total energy with respect to the atomic interplane distance. A body-centered tetragonal (BCT) pseudomorphic crystalline structure with a tetragonality ratio c/a larger than unity is found. The magnetic behaviour is characterized by an enhanced magnetic moment and a ferromagnetic interplane coupling. The polar magneto-optical Kerr effect spectra are given over a photon energy range extended to 15eV and the microscopic origin of the most interesting features are interpreted by interband transitions. Unlike thin layers, the anisotropy in the ultra-thin films is characterized by a perpendicular magnetization which is perpendicular to the film plane. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ultrathin%20films" title="ultrathin films">ultrathin films</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetism" title=" magnetism"> magnetism</a>, <a href="https://publications.waset.org/abstracts/search?q=magneto-optics" title=" magneto-optics"> magneto-optics</a>, <a href="https://publications.waset.org/abstracts/search?q=pseudomorphic%20structure" title=" pseudomorphic structure"> pseudomorphic structure</a> </p> <a href="https://publications.waset.org/abstracts/25728/theoretical-study-of-structural-magnetic-and-magneto-optical-properties-of-ultrathin-films-of-fecu-001" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25728.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">335</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14774</span> Stimulated Raman Scattering of Ultra Intense Hollow Gaussian Beam</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Prerana%20Sharma">Prerana Sharma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Effect of relativistic nonlinearity on stimulated Raman scattering of the propagating laser beam carrying null intensity in center (hollow Gaussian beam) by excited plasma wave are studied in a collisionless plasma.

In this paper, we expand the vector fields associated to infinitesimal symmetries which give rise to invariant quantities as Noether currents for classical field theories and relativistic mechanic using the multisymplectic geometry where the Poincaré-Cartan form has thus been greatly simplified using the Second Order Partial Differential Equation (SOPDE) for multi-vector fields verifying Euler equations. These symmetries have been classified naturally according to the construction of the fiber bundle used.  In this work, unlike other works using the analytical method, our geometric model has allowed us firstly to distinguish the angular moments of the gauge field obtained during different transformations while these moments are gathered in a single expression and are obtained during a rotation in the Minkowsky space. Secondly, no conditions are imposed on the Lagrangian of the mechanics with respect to its dependence in time and in q<sup>i</sup>, the currents obtained naturally from the transformations are respectively the energy and the momentum of the system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conservation%20laws" title="conservation laws">conservation laws</a>, <a href="https://publications.waset.org/abstracts/search?q=field%20theories" title=" field theories"> field theories</a>, <a href="https://publications.waset.org/abstracts/search?q=multisymplectic%20geometry" title=" multisymplectic geometry"> multisymplectic geometry</a>, <a href="https://publications.waset.org/abstracts/search?q=relativistic%20mechanics" title=" relativistic mechanics"> relativistic mechanics</a> </p> <a href="https://publications.waset.org/abstracts/74108/multisymplectic-geometry-and-noether-symmetries-for-the-field-theories-and-the-relativistic-mechanics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74108.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">206</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14772</span> Central Finite Volume Methods Applied in Relativistic Magnetohydrodynamics: Applications in Disks and Jets</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raphael%20de%20Oliveira%20Garcia">Raphael de Oliveira Garcia</a>, <a href="https://publications.waset.org/abstracts/search?q=Samuel%20Rocha%20de%20Oliveira"> Samuel Rocha de Oliveira</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We have developed a new computer program in Fortran 90, in order to obtain numerical solutions of a system of Relativistic Magnetohydrodynamics partial differential equations with predetermined gravitation (GRMHD), capable of simulating the formation of relativistic jets from the accretion disk of matter up to his ejection. Initially we carried out a study on numerical methods of unidimensional Finite Volume, namely Lax-Friedrichs, Lax-Wendroff, Nessyahu-Tadmor method and Godunov methods dependent on Riemann problems, applied to equations Euler in order to verify their main features and make comparisons among those methods. It was then implemented the method of Finite Volume Centered of Nessyahu-Tadmor, a numerical schemes that has a formulation free and without dimensional separation of Riemann problem solvers, even in two or more spatial dimensions, at this point, already applied in equations GRMHD. Finally, the Nessyahu-Tadmor method was possible to obtain stable numerical solutions - without spurious oscillations or excessive dissipation - from the magnetized accretion disk process in rotation with respect to a central black hole (BH) Schwarzschild and immersed in a magnetosphere, for the ejection of matter in the form of jet over a distance of fourteen times the radius of the BH, a record in terms of astrophysical simulation of this kind. Also in our simulations, we managed to get substructures jets.

Boltzmann’s law and the Maxwell-Boltzmann distribution describe the distribution of velocity of a particle in plasma as a function of mass and temperature. Particles with the same mass tend to have the same velocity. By expressing the same law in terms of energy alone, the author obtains a distribution independent of mass. In summary, for particles in plasma, the energies tend to equalize, independent of the masses of the individual particles. For high-energy plasma, the original law predicts velocities greater than the speed of light. If one uses Einstein’s formula for energy (<em>E=mc<sup>2</sup></em>), then a relativistic correction is not required. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cosmology" title="cosmology">cosmology</a>, <a href="https://publications.waset.org/abstracts/search?q=EMP" title=" EMP"> EMP</a>, <a href="https://publications.waset.org/abstracts/search?q=plasma%20physics" title=" plasma physics"> plasma physics</a>, <a href="https://publications.waset.org/abstracts/search?q=relativity" title=" relativity"> relativity</a> </p> <a href="https://publications.waset.org/abstracts/84272/a-unification-and-relativistic-correction-for-boltzmanns-law" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84272.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">219</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14770</span> Radiation Emission from Ultra-Relativistic Plasma Electrons in Short-Pulse Laser Light Interactions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20Ondarza-Rovira">R.

When the laser pulse is p-polarized, plasma effects do modify the harmonic spectrum, weakening the so-called universal decay with p=8/3 to p=5/3, or below. In this work, appeal is made to a single particle radiation model in support of the predictions from particle-in-cell (PIC) simulations. Using this numerical technique we further show that the emission radiated by electrons -that are relativistically accelerated by the laser field inside the plasma, after being expelled into vacuum, the so-called Brunel electrons is characterized not only by the plasma line but also by ultraviolet harmonic orders described by the 5/3 decay index. Results obtained from these simulations suggest that for ultra-relativistic light intensities, the spectral decay index is further reduced, with p now in the range 2/3 ≤ p ≤ 4/3. This reduction is indicative of a transition from the regime where Brunel-induced plasma radiation influences the spectrum to one dominated by bremsstrahlung emission from the Brunel electrons. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ultra-relativistic" title="ultra-relativistic">ultra-relativistic</a>, <a href="https://publications.waset.org/abstracts/search?q=laser-plasma%20interactions" title=" laser-plasma interactions"> laser-plasma interactions</a>, <a href="https://publications.waset.org/abstracts/search?q=high-order%20harmonic%20emission" title=" high-order harmonic emission"> high-order harmonic emission</a>, <a href="https://publications.waset.org/abstracts/search?q=radiation" title=" radiation"> radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=spectrum" title=" spectrum "> spectrum </a> </p> <a href="https://publications.waset.org/abstracts/27628/radiation-emission-from-ultra-relativistic-plasma-electrons-in-short-pulse-laser-light-interactions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27628.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">464</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14769</span> Periodic Change in the Earth’s Rotation Velocity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sung%20Duk%20Kim">Sung Duk Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Kwan%20U.%20Kim"> Kwan U.

According to the previous investigation, atmospheric circulation is supposed to be a factor affecting the seasonal variations in the Earth’s rotation velocity in many cases, but the problem has not been solved yet. In order to solve the problem, it is necessary to apply dynamics to consider the Earth’s spatial motion, rotation, and change of shape of the Earth (movement of materials in and out of the Earth and change of the Earth’s figure) at the same time and in interrelation to the accuracy of post-Newtonian approximation regarding the Earth body as a system of mass points because the stability of the Earth’s rotation angular velocity is in the range of 10⁻⁸~10⁻⁹. For it, the equation was derived, which can consider the 3 kinds of motion above mentioned at the same time by taking the effect of the resultant external force on the Earth’s rotation into account in a relativistic way to the accuracy of post-Newtonian approximation. Therefore, the equation has been solved to obtain the theoretical values of periodic change in the Earth’s rotation velocity, and they have been compared with the astronomical observation data so to reveal the cause for the periodic change in the Earth’s rotation velocity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Earth%20rotation" title="Earth rotation">Earth rotation</a>, <a href="https://publications.waset.org/abstracts/search?q=moment%20function" title=" moment function"> moment function</a>, <a href="https://publications.waset.org/abstracts/search?q=periodic%20change" title=" periodic change"> periodic change</a>, <a href="https://publications.waset.org/abstracts/search?q=seasonal%20variation" title=" seasonal variation"> seasonal variation</a>, <a href="https://publications.waset.org/abstracts/search?q=relativistic%20change" title=" relativistic change"> relativistic change</a> </p> <a href="https://publications.waset.org/abstracts/182897/periodic-change-in-the-earths-rotation-velocity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182897.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">73</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14768</span> Ground State Properties of Neutron Magic Isotones</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G.%20Saxena">G.

The entangled pair formed by the upper and lower sideband peaks is bound by the angular displacement, which is given by 0≤θ≤π/2. The control signals associated with 3-peak signal frequencies are applied by the external inputs via the microstrip add-drop multiplexer ports, where they are time functions without the space term involved. When a system satisfies the speed of light conditions, the mass term has been changed to energy based on the relativistic limit described by the Lorentz factor and Einstein equation. The different applied frequencies can be utilized to form the 3-phase torques that can be applied for quantum engines. The experiment will use the two-level system circuit and be conducted in the laboratory. The 3-phase torques will be recorded and investigated for quantum engine driving purpose. The obtained results will be compared to the simulation. The optimum amplification of torque can be obtained by the resonant successive filtering operation. Torque will be vanished when the system is balanced at the stopped position, where |Time|=0, which is required to be a system stability condition. It will be discussed for future applications. A larger device may be tested in the future for realistic use.

The amount of the precession of the perihelion for Einstein’s theory of gravitation has been explained by means of the inverse fourth power force(inverse third power potential) introduced totheory of gravitation through Schwarzschild metric However, the methodology has a serious shortcoming that it is impossible to explain the cause for the precession of the perihelion in the planetary orbits. According to our study, without taking the cause for the precession of the perihelion, 6 methods can explain the amount of the precession of the perihelion discovered by Leverrier. Therefore, the problem of what caused the perihelion to precess in the planetary orbits must be solved for physics because it is a profound scientific and technological problem for a basic experiment in construction of relativistic theory of gravitation. The scientific solution to the problem proved that Einstein’s explanation for the planetary orbits is a magic made by the numerical expressions obtained from fictitious gravitation introduced to theory of gravitation and wrong definition of proper time The problem of the precession of the perihelion seems solved already by means of general theory of relativity, but, in essence, the cause for the astronomical phenomenon has not been successfully explained for astronomy yet. The right solution to the problem comes from generalized theory of gravitation. Therefore, in this paper, it has been shown that by means of Schwarzschild field and the physical quantities of relativistic Lagrangian redflected in it, fictitious gravitation is not the main factor which can cause the perihelion to precess in the planetary orbits. In addition to it, it has been shown that the main factor which can cause the perihelion to precess in the planetary orbits is the inverse third power force existing really in the relativistic region in the Solar system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inverse%20third%20power%20force" title="inverse third power force">inverse third power force</a>, <a href="https://publications.waset.org/abstracts/search?q=precession%20of%20the%20perihelion" title=" precession of the perihelion"> precession of the perihelion</a>, <a href="https://publications.waset.org/abstracts/search?q=fictitious%20gravitation" title=" fictitious gravitation"> fictitious gravitation</a>, <a href="https://publications.waset.org/abstracts/search?q=planetary%20orbits" title=" planetary orbits"> planetary orbits</a> </p> <a href="https://publications.waset.org/abstracts/192598/causes-for-the-precession-of-the-perihelion-in-the-planetary-orbits" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192598.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">10</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14765</span> Study of Electron Cyclotron Resonance Acceleration by Cylindrical TE₀₁₁ Mode</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oswaldo%20Otero">Oswaldo Otero</a>, <a href="https://publications.waset.org/abstracts/search?q=Eduardo%20A.%20Orozco"> Eduardo A.

The stability of the orbits is analyzed using the particle orbit theory. In order to get a better understanding of the interaction wave-particle, we decompose the azimuthally electric field component as the superposition of right and left-hand circular polarization standing waves. The trajectory, energy and phase-shift of the electron are found through a numerical solution of the relativistic Newton-Lorentz equation in a finite difference method by the Boris method. It is shown that an electron longitudinally injected with an energy of 7 keV in a radial position r=Rc/2, being Rc the cavity radius, is accelerated up to energy of 90 keV by an electric field strength of 14 kV/cm and frequency of 2.45 GHz. This energy can be used to produce X-ray for medical imaging. These results can be used as a starting point for study the acceleration of electrons in a magnetic field changing slowly in time (GYRAC), which has some important applications as the electron cyclotron resonance ion proton accelerator (ECR-IPAC) for cancer therapy and to control plasma bunches with relativistic electrons. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Boris%20method" title="Boris method">Boris method</a>, <a href="https://publications.waset.org/abstracts/search?q=electron%20cyclotron%20resonance" title=" electron cyclotron resonance"> electron cyclotron resonance</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20difference%20method" title=" finite difference method"> finite difference method</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20orbit%20theory" title=" particle orbit theory"> particle orbit theory</a>, <a href="https://publications.waset.org/abstracts/search?q=X-ray" title=" X-ray"> X-ray</a> </p> <a href="https://publications.waset.org/abstracts/98818/study-of-electron-cyclotron-resonance-acceleration-by-cylindrical-te011-mode" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98818.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">159</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14764</span> Quantum Mechanics as A Limiting Case of Relativistic Mechanics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Almajid">Ahmad Almajid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The idea of unifying quantum mechanics with general relativity is still a dream for many researchers, as physics has only two paths, no more. Einstein's path, which is mainly based on particle mechanics, and the path of Paul Dirac and others, which is based on wave mechanics, the incompatibility of the two approaches is due to the radical difference in the initial assumptions and the mathematical nature of each approach. Logical thinking in modern physics leads us to two problems: - In quantum mechanics, despite its success, the problem of measurement and the problem of wave function interpretation is still obscure. - In special relativity, despite the success of the equivalence of rest-mass and energy, but at the speed of light, the fact that the energy becomes infinite is contrary to logic because the speed of light is not infinite, and the mass of the particle is not infinite too. These contradictions arise from the overlap of relativistic and quantum mechanics in the neighborhood of the speed of light, and in order to solve these problems, one must understand well how to move from relativistic mechanics to quantum mechanics, or rather, to unify them in a way different from Dirac's method, in order to go along with God or Nature, since, as Einstein said, "God doesn't play dice." From De Broglie's hypothesis about wave-particle duality, Léon Brillouin's definition of the new proper time was deduced, and thus the quantum Lorentz factor was obtained. Finally, using the Euler-Lagrange equation, we come up with new equations in quantum mechanics. In this paper, the two problems in modern physics mentioned above are solved; it can be said that this new approach to quantum mechanics will enable us to unify it with general relativity quite simply. If the experiments prove the validity of the results of this research, we will be able in the future to transport the matter at speed close to the speed of light. Finally, this research yielded three important results: 1- Lorentz quantum factor. 2- Planck energy is a limited case of Einstein energy. 3- Real quantum mechanics, in which new equations for quantum mechanics match and exceed Dirac's equations, these equations have been reached in a completely different way from Dirac's method. These equations show that quantum mechanics is a limited case of relativistic mechanics. At the Solvay Conference in 1927, the debate about quantum mechanics between Bohr, Einstein, and others reached its climax, while Bohr suggested that if particles are not observed, they are in a probabilistic state, then Einstein said his famous claim ("God does not play dice"). Thus, Einstein was right, especially when he didn't accept the principle of indeterminacy in quantum theory, although experiments support quantum mechanics. However, the results of our research indicate that God really does not play dice; when the electron disappears, it turns into amicable particles or an elastic medium, according to the above obvious equations. Likewise, Bohr was right also, when he indicated that there must be a science like quantum mechanics to monitor and study the motion of subatomic particles, but the picture in front of him was blurry and not clear, so he resorted to the probabilistic interpretation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lorentz%20quantum%20factor" title="lorentz quantum factor">lorentz quantum factor</a>, <a href="https://publications.waset.org/abstracts/search?q=new" title=" new"> new</a>, <a href="https://publications.waset.org/abstracts/search?q=planck%E2%80%99s%20energy%20as%20a%20limiting%20case%20of%20einstein%E2%80%99s%20energy" title=" planck’s energy as a limiting case of einstein’s energy"> planck’s energy as a limiting case of einstein’s energy</a>, <a href="https://publications.waset.org/abstracts/search?q=real%20quantum%20mechanics" title=" real quantum mechanics"> real quantum mechanics</a>, <a href="https://publications.waset.org/abstracts/search?q=new%20equations%20for%20quantum%20mechanics" title=" new equations for quantum mechanics"> new equations for quantum mechanics</a> </p> <a href="https://publications.waset.org/abstracts/159579/quantum-mechanics-as-a-limiting-case-of-relativistic-mechanics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159579.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">77</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14763</span> Comparison of Two Theories for the Critical Laser Radius in Thermal Quantum Plasma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Somaye%20Zare">Somaye Zare</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The critical beam radius is a significant factor that predicts the behavior of the laser beam in the plasma, so if the laser beam radius is adequately greater in comparison to it, the beam will experience stable focusing on the plasma; otherwise, the beam will diverge after entering into the plasma. In this work, considering the paraxial approximation and moment theories, the localization of a relativistic laser beam in thermal quantum plasma is investigated. Using the dielectric function obtained in the quantum hydrodynamic model, the mathematical equation for the laser beam width parameter is attained and solved numerically by the fourth-order Runge-Kutta method. The results demonstrate that the stouter focusing effect is occurred in the moment theory compared to the paraxial approximation. Besides, similar to the two theories, with increasing Fermi temperature, plasma density, and laser intensity, the oscillation rate of the beam width parameter growths and focusing length reduces which means improving the focusing effect. Furthermore, it is understood that behaviors of the critical laser radius are different in the two theories, in the paraxial approximation, the critical radius after a minimum value is enhanced with increasing laser intensity, but in the moment theory, with increasing laser intensity, the critical radius decreases until it becomes independent of the laser intensity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=laser%20localization" title="laser localization">laser localization</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20plasma" title=" quantum plasma"> quantum plasma</a>, <a href="https://publications.waset.org/abstracts/search?q=paraxial%20approximation" title=" paraxial approximation"> paraxial approximation</a>, <a href="https://publications.waset.org/abstracts/search?q=moment%20theory" title=" moment theory"> moment theory</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20hydrodynamic%20model" title=" quantum hydrodynamic model"> quantum hydrodynamic model</a> </p> <a href="https://publications.waset.org/abstracts/171090/comparison-of-two-theories-for-the-critical-laser-radius-in-thermal-quantum-plasma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171090.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">72</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14762</span> Measurements of Scattering Cross Sections for 5.895 keV Photons in Various Polymers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Duggal">H.

The experimental measurements were carried out using the energy dispersive setup involving annular source of the 55Fe radioisotope and a low energy germanium (LEGe) detector. The cross section values are measured for 20 polymer targets namely, Paraffin Wax, Polytetrafluoro ethylene (PTFE), Cellulose, Silicone oil, Polyvinyl alcohol (PVA), Polyvinyl purrolidone (PVP), Polymethyl methacrylate (PMMA), Kapton, Mylar, Chitosan, Polyvinyl chloride (PVC), Bakelite, Carbopol, Chlorobutyl rubber (CBR), Polyetylene glycol (PEG), Polysorbate-20, Nylon-6, Cetyl alcohol, Carboxyl methyl sodium cellulose and Sodium starch glucolate. The measurements were performed in vacuum so as to avoid scattering contribution due to air and strong absorption of low energy photons in the air column. In the present investigations, the geometrical factor and efficiency of the detector were determined by measuring the K x-rays emitted from the 22Ti and 23V targets excited by the Mn K x-rays in the same experimental set up. The measured scattering cross sections have been compared with the sum of theoretically calculated elastic and inelastic scattering cross sections. The theoretical elastic (Rayleigh) scattering cross sections based on the various form factor approximations, namely, non-relativistic form factor (NF), relativistic form factor (RF), modified form factor (MF), and MF with anomalous scattering factor (ASF) as well as the second order S-matrix formalisms, and the inelastic scattering differential cross sections based on the Klein-Nishina formula after including the inelastic scattering function (KN+ISF) have been calculated. The experimental results show fairly good agreement with theoretical cross sections. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=photon" title="photon">photon</a>, <a href="https://publications.waset.org/abstracts/search?q=polymers" title=" polymers"> polymers</a>, <a href="https://publications.waset.org/abstracts/search?q=elastic%20and%20inelastic" title=" elastic and inelastic"> elastic and inelastic</a>, <a href="https://publications.waset.org/abstracts/search?q=scattering%20cross%20sections" title=" scattering cross sections"> scattering cross sections</a> </p> <a href="https://publications.waset.org/abstracts/15642/measurements-of-scattering-cross-sections-for-5895-kev-photons-in-various-polymers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15642.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">689</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14761</span> Realizing Teleportation Using Black-White Hole Capsule Constructed by Space-Time Microstrip Circuit Control</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mapatsakon%20Sarapat">Mapatsakon Sarapat</a>, <a href="https://publications.waset.org/abstracts/search?q=Mongkol%20Ketwongsa"> Mongkol Ketwongsa</a>, <a href="https://publications.waset.org/abstracts/search?q=Somchat%20Sonasang"> Somchat Sonasang</a>, <a href="https://publications.waset.org/abstracts/search?q=Preecha%20Yupapin"> Preecha Yupapin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The designed and performed preliminary tests on a space-time control circuit using a two-level system circuit with a 4-5 cm diameter microstrip for realistic teleportation have been demonstrated. It begins by calculating the parameters that allow a circuit that uses the alternative current (AC) at a specified frequency as the input signal. A method that causes electrons to move along the circuit perimeter starting at the speed of light, which found satisfaction based on the wave-particle duality. It is able to establish the supersonic speed (faster than light) for the electron cloud in the middle of the circuit, creating a timeline and propulsive force as well. The timeline is formed by the stretching and shrinking time cancellation in the relativistic regime, in which the absolute time has vanished. In fact, both black holes and white holes are created from time signals at the beginning, where the speed of electrons travels close to the speed of light. They entangle together like a capsule until they reach the point where they collapse and cancel each other out, which is controlled by the frequency of the circuit. Therefore, we can apply this method to large-scale circuits such as potassium, from which the same method can be applied to form the system to teleport living things. In fact, the black hole is a hibernation system environment that allows living things to live and travel to the destination of teleportation, which can be controlled from position and time relative to the speed of light. When the capsule reaches its destination, it increases the frequency of the black holes and white holes canceling each other out to a balanced environment. Therefore, life can safely teleport to the destination. Therefore, there must be the same system at the origin and destination, which could be a network. Moreover, it can also be applied to space travel as well. The design system will be tested on a small system using a microstrip circuit system that we can create in the laboratory on a limited budget that can be used in both wired and wireless systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=quantum%20teleportation" title="quantum teleportation">quantum teleportation</a>, <a href="https://publications.waset.org/abstracts/search?q=black-white%20hole" title=" black-white hole"> black-white hole</a>, <a href="https://publications.waset.org/abstracts/search?q=time" title=" time"> time</a>, <a href="https://publications.waset.org/abstracts/search?q=timeline" title=" timeline"> timeline</a>, <a href="https://publications.waset.org/abstracts/search?q=relativistic%20electronics" title=" relativistic electronics"> relativistic electronics</a> </p> <a href="https://publications.waset.org/abstracts/175534/realizing-teleportation-using-black-white-hole-capsule-constructed-by-space-time-microstrip-circuit-control" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175534.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">75</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14760</span> Meditation and Insight Interpretation Using Quantum Circle Based-on Experiment and Quantum Relativity Formalism</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Somnath%20Bhattachryya">Somnath Bhattachryya</a>, <a href="https://publications.waset.org/abstracts/search?q=Montree%20Bunruangses"> Montree Bunruangses</a>, <a href="https://publications.waset.org/abstracts/search?q=Somchat%20Sonasang"> Somchat Sonasang</a>, <a href="https://publications.waset.org/abstracts/search?q=Preecha%20Yupapin"> Preecha Yupapin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study and research on meditation and insight, the design and experiment with electronic circuits to manipulate the meditators' mental circles that call the chakras to have the same size is proposed. The shape of the circuit is 4-ports, called an add-drop multiplexer, that studies the meditation structure called the four-mindfulness foundation, then uses an AC power signal as an input instead of the meditation time function, where various behaviors with the method of re-filtering the signal (successive filtering), like eight noble paths. Start by inputting a signal at a frequency that causes the velocity of the wave on the perimeter of the circuit to cause particles to have the speed of light in a vacuum. The signal changes from electromagnetic waves and matter waves according to the velocity (frequency) until it reaches the point of the relativistic limit. The electromagnetic waves are transformed into photons with properties of wave-particle overcoming the limits of the speed of light. As for the matter wave, it will travel to the other side and cannot pass through the relativistic limit, called a shadow signal (echo) that can have power from increasing speed but cannot create speed faster than light or insight. In the experiment, the only the side where the velocity is positive, only where the speed above light or the corresponding frequency indicates intelligence. Other side(echo) can be done by changing the input signal to the other side of the circuit to get the same result. But there is no intelligence or speed beyond light. It is also used to study the stretching, contraction of time and wormholes that can be applied for teleporting, Bose-Einstein condensate and teleprinting, quantum telephone. The teleporting can happen throughout the system with wave-particle and echo, which is when the speed of the particle is faster than the stretching or contraction of time, the particle will submerge in the wormhole, when the destination and time are determined, will travel through the wormhole. In a wormhole, time can determine in the future and the past.

The mechanism responsible for the self-focusing of a laser beam in plasma is considered to be the relativistic mass variation of plasma electrons under the effect of a highly intense laser beam. Using the moment theory approach and considering the Wentzel-Kramers-Brillouin approximation for the non-linear Schrodinger wave equation, the differential equation is derived, which governs the spot size of the higher-order Gaussian laser beam in plasma. The nonlinearity induced by the laser beam creates the density gradient in the background plasma electrons, which is responsible for the excitation of the electron plasma wave. The large amplitude electron plasma wave interacts with the fundamental beam, which further produces the coherent radiations with double the frequency of the incident beam. The analysis shows the important role of the different modes of higher-order Gaussian laser beam and density ramp on the efficiency of generated harmonics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=density%20rippled%20plasma" title="density rippled plasma">density rippled plasma</a>, <a href="https://publications.waset.org/abstracts/search?q=higher%20order%20Gaussian%20laser%20beam" title=" higher order Gaussian laser beam"> higher order Gaussian laser beam</a>, <a href="https://publications.waset.org/abstracts/search?q=moment%20theory%20approach" title=" moment theory approach"> moment theory approach</a>, <a href="https://publications.waset.org/abstracts/search?q=second%20harmonic%20generation." title=" second harmonic generation.

Today, Islam is regarded as one of the fastest growing religions in the world, another peaceful one and very accommodating to other religions. Politics dominates in Islam and, as a result, divisions into various groupings, including the Ahmadiyah, Tijania, Suni and many others. Despite all believing the Qur’an as the only holy book used, they are all affiliated with different types of hadiths, including the al-Nawawi’s. These divisions are the reasons for tension in Islam, and it is necessary to conduct this research to investigate political situations in Islam within the society. Over the past three or two decades, there have been diverse and divided opinions about politics and religion (Islam). Many believe that politics and religion are inherently subjective and should be accepted as such, and the further argument for a relativistic approach is that individuals' and communities’ beliefs and values should be acknowledged and respected since no single political or religious ideology can claim absolute truth and superiority over the other. The perspective view is that emphasis is placed on tolerance and coexistence between different political and religious views; moreover, society is comprised of individuals with different backgrounds, opinions and interests, so it is necessary to find common ground and create space where diverse ideas can peacefully coexist in order to promote dialogue, understanding and mutual respect to maintain social harmony and peaceful relation in the society. Also, some individuals in society argue about the universalism of certain moral principles, which should be certain and agreed upon by all. For example, the Jewish people believe that eating pork is wrong, and if someone of another religion is asked if they agree with that, objectively, the non-Jewish would be comfortable with that. Others still argue that a continuous relativistic approach to politics and religion can lead to a breakdown of shared moral standards, loss of ethical principles, doubting faith or loyalty and uprising against agencies of politics and religion. And within the political groupings, they believe in the same ideologies to propagate their message, likewise the religious belongings (Christianity, Islam, Judaism and others) who also ensure that their religious perspectives or beliefs are deeply rooted in the society. This forms the basis for research about the perspective of politics and religious relativism in this modern era to respond to the questions and the challenges of religious politics in Islam. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=relativism" title="relativism">relativism</a>, <a href="https://publications.waset.org/abstracts/search?q=religion" title=" religion"> religion</a>, <a href="https://publications.waset.org/abstracts/search?q=universality" title=" universality"> universality</a>, <a href="https://publications.waset.org/abstracts/search?q=politics" title=" politics"> politics</a> </p> <a href="https://publications.waset.org/abstracts/173008/the-perspectives-of-the-society-regarding-relativism-of-politics-and-religion-islam-in-modern-era" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173008.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">64</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14757</span> Electrostatic Solitary Waves in Degenerate Relativistic Quantum Plasmas</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sharmin%20Sultana">Sharmin Sultana</a>, <a href="https://publications.waset.org/abstracts/search?q=Reinhard%20Schlickeiser"> Reinhard Schlickeiser</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A degenerate relativistic quantum plasma (DRQP) system (containing relativistically degenerate electrons, degenerate/non-degenerate light nuclei, and non-degenerate heavy nuclei) is considered to investigate the propagation characteristics of electrostatic solitary waves (in the ionic scale length) theoretically and numerically. The ion-acoustic solitons are found to be associated with the modified ion-acoustic waves (MIAWs) in which inertia (restoring force) is provided by mass density of the light or heavy nuclei (degenerate pressure of the cold electrons). A mechanical-motion analog (Sagdeev-type) pseudo-potential approach is adopted to study the properties of large amplitude solitary waves. The basic properties of the large amplitude MIAWs and their existence domain in terms of soliton speed (Mach number) are examined. On the other hand, a multi-scale perturbation approach, leading to an evolution equation for the envelope dynamics, is adopted to derive the cubic nonlinear Schrödinger equation (NLSE). The criteria for the occurrence of modulational instability (MI) of the MIAWs are analyzed via the nonlinear dispersion relation of the NLSE. The possibility for the formation of highly energetic localized modes (e.g. peregrine solitons, rogue waves, etc.) is predicted in such DRQP medium. Peregrine solitons or rogue waves with amplitudes of several times of the background are observed to form in DRQP. The basic features of these modulated waves (e.g. envelope solitons, peregrine solitons, and rogue waves), which are found to form in DRQP, and their MI criteria (on the basis of different intrinsic plasma parameters), are investigated. It is emphasized that our results should be useful in understanding the propagation characteristics of localized disturbances and the modulation dynamics of envelope solitons, and their instability criteria in astrophysical DRQP system (e.g. white dwarfs, neutron stars, etc., where matters under extreme conditions are assumed to exist) and also in ultra-high density experimental plasmas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=degenerate%20plasma" title="degenerate plasma">degenerate plasma</a>, <a href="https://publications.waset.org/abstracts/search?q=envelope%20solitons" title=" envelope solitons"> envelope solitons</a>, <a href="https://publications.waset.org/abstracts/search?q=modified%20ion-acoustic%20waves" title=" modified ion-acoustic waves"> modified ion-acoustic waves</a>, <a href="https://publications.waset.org/abstracts/search?q=modulational%20instability" title=" modulational instability"> modulational instability</a>, <a href="https://publications.waset.org/abstracts/search?q=rogue%20waves" title=" rogue waves"> rogue waves</a> </p> <a href="https://publications.waset.org/abstracts/80187/electrostatic-solitary-waves-in-degenerate-relativistic-quantum-plasmas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80187.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">203</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14756</span> Hawking Radiation of Grumiller Black </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sherwan%20Kher%20Alden%20Yakub%20Alsofy">Sherwan Kher Alden Yakub Alsofy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we consider the relativistic Hamilton-Jacobi (HJ) equation and study the Hawking radiation (HR) of scalar particles from uncharged Grumiller black hole (GBH) which is aﬀordable for testing in astrophysics. GBH is also known as Rindler modiﬁed Schwarzschild BH. Our aim is not only to investigate the eﬀect of the Rindler parameter A on the Hawking temperature (TH ), but to examine whether there is any discrepancy between the computed horizon temperature and the standard TH as well. For this purpose, in addition to its naive coordinate system, we study on the three regular coordinate systems which are Painlev´-Gullstrand (PG), ingoing Eddington- Finkelstein (IEF) and Kruskal-Szekeres (KS) coordinates. In all coordinate systems, we calculate the tunneling probabilities of incoming and outgoing scalar particles from the event horizon by using the HJ equation. It has been shown in detail that the considered HJ method is concluded with the conventional TH in all these coordinate systems without giving rise to the famous factor- 2 problem. Furthermore, in the PG coordinates Parikh-Wilczek’s tunneling (PWT) method is employed in order to show how one can integrate the quantum gravity (QG) corrections to the semiclassical tunneling rate by including the eﬀects of self-gravitation and back reaction. We then show how these corrections yield a modiﬁcation in the TH. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ingoing%20Eddington"
