In part of the tests, boron-nitride (BN) was added to the polymer. Our experiments with resonant nanoantennas accelerated protons up to 225 keV energy. Some of these protons then led to p + 11B fusion, indicated by the sharp drop of observed backward proton emission numbers at the 150 keV resonance energy of the reaction. The generation of alpha particles was verified by CR-39 (Columbia Resin #39) nuclear plastic track detectors. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2411.09796v1-abstract-full').style.display = 'none'; document.getElementById('2411.09796v1-abstract-short').style.display = 'inline';">&#9651; Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 14 November, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> November 2024. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">14 pages, 4 figures</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2402.18138">arXiv:2402.18138</a> <span>&nbsp;[<a href="https://arxiv.org/pdf/2402.18138">pdf</a>]&nbsp;</span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Optics">physics.optics</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Plasma Physics">physics.plasm-ph</span> </div> </div> <p class="title is-5 mathjax"> Pulsed laser intensity dependence of crater formation and light reflection in the UDMA-TEGDMA copolymer nanocomposite, doped with resonant plasmonic gold nanorods </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&amp;query=Szokol%2C+%C3%81+N">脕gnes Nagyn茅 Szokol</a>, <a href="/search/physics?searchtype=author&amp;query=K%C3%A1m%C3%A1n%2C+J">Judit K谩m谩n</a>, <a href="/search/physics?searchtype=author&amp;query=Holomb%2C+R">Roman Holomb</a>, <a href="/search/physics?searchtype=author&amp;query=Aladi%2C+M">M谩rk Aladi</a>, <a href="/search/physics?searchtype=author&amp;query=Kedves%2C+M">Mikl贸s Kedves</a>, <a href="/search/physics?searchtype=author&amp;query=R%C3%A1czkevi%2C+B">B茅la R谩czkevi</a>, <a href="/search/physics?searchtype=author&amp;query=R%C3%A1cz%2C+P">P茅ter R谩cz</a>, <a href="/search/physics?searchtype=author&amp;query=Bony%C3%A1r%2C+A">Attila Bony谩r</a>, <a href="/search/physics?searchtype=author&amp;query=Bor%C3%B3k%2C+A">Alexandra Bor贸k</a>, <a href="/search/physics?searchtype=author&amp;query=Zangana%2C+S">Shereen Zangana</a>, <a href="/search/physics?searchtype=author&amp;query=Szal%C3%B3ki%2C+M">Melinda Szal贸ki</a>, <a href="/search/physics?searchtype=author&amp;query=Papp%2C+I">Istv谩n Papp</a>, <a href="/search/physics?searchtype=author&amp;query=Galb%C3%A1cs%2C+G">G谩bor Galb谩cs</a>, <a href="/search/physics?searchtype=author&amp;query=Bir%C3%B3%2C+T+S">Tam谩s S.

In this study, excess energy creation was observed during the single-shot irradiation of a polymer matrix containing plasmonic gold nanorods, resonant to the laser wavelength, with a high intensity femtosecond laser pulse. This effect was manifested in a 7-fold rise in the crater volume for a 1.7-fold increase of the laser intensity, and was absent in the pure polymer without the gold doping. It occurred at laser intensities &gt; 1.5 x 1017 W/cm2, being the vanishing threshold of plasma mirror formation, resulting in a more than 80% increase of the amount of laser light entering the target. This threshold was found to be critical for the plasmonic effect of gold nanoantennas tuned to the wavelength of the laser on the crater formation. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2402.18138v1-abstract-full').style.display = 'none'; document.getElementById('2402.18138v1-abstract-short').style.display = 'inline';">&#9651; Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 28 February, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> February 2024. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">13 pages, 5 figures</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2312.16723">arXiv:2312.16723</a> <span>&nbsp;[<a href="https://arxiv.org/pdf/2312.16723">pdf</a>]&nbsp;</span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Plasma Physics">physics.plasm-ph</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Optics">physics.optics</span> </div> </div> <p class="title is-5 mathjax"> Monitoring of nanoplasmonics-assisted deuterium production in a polymer seeded with resonant Au nanorods using in situ femtosecond laser induced breakdown spectroscopy </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&amp;query=Kro%C3%B3%2C+N">N.

The observed effect is attributed only to the field enhancing effects due to excited localized surface plasmons on the gold nanoparticles. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2312.16723v1-abstract-full').style.display = 'none'; document.getElementById('2312.16723v1-abstract-short').style.display = 'inline';">&#9651; Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 27 December, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> December 2023. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2210.00619">arXiv:2210.00619</a> <span>&nbsp;[<a href="https://arxiv.org/pdf/2210.00619">pdf</a>]&nbsp;</span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Plasma Physics">physics.plasm-ph</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Optics">physics.optics</span> </div> </div> <p class="title is-5 mathjax"> Raman spectroscopic characterization of crater walls formed upon single-shot high energy femtosecond laser irradiation of dimethacrylate polymer doped with plasmonic gold nanorods </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&amp;query=Rig%C3%B3%2C+I">Istv谩n Rig贸</a>, <a href="/search/physics?searchtype=author&amp;query=K%C3%A1m%C3%A1n%2C+J">Judit K谩m谩n</a>, <a href="/search/physics?searchtype=author&amp;query=Szokol%2C+%C3%81+N">脕gnes Nagyn茅 Szokol</a>, <a href="/search/physics?searchtype=author&amp;query=Bony%C3%A1r%2C+A">Attila Bony谩r</a>, <a href="/search/physics?searchtype=author&amp;query=Szal%C3%B3ki%2C+M">Melinda Szal贸ki</a>, <a href="/search/physics?searchtype=author&amp;query=Bor%C3%B3k%2C+A">Alexandra Bor贸k</a>, <a href="/search/physics?searchtype=author&amp;query=Zangana%2C+S">Shereen Zangana</a>, <a href="/search/physics?searchtype=author&amp;query=R%C3%A1cz%2C+P">P茅ter R谩cz</a>, <a href="/search/physics?searchtype=author&amp;query=Aladi%2C+M">M谩rk Aladi</a>, <a href="/search/physics?searchtype=author&amp;query=Kedves%2C+M+%C3%81">Mikl贸s 脕kos Kedves</a>, <a href="/search/physics?searchtype=author&amp;query=Galb%C3%A1cs%2C+G">G谩bor Galb谩cs</a>, <a href="/search/physics?searchtype=author&amp;query=Csernai%2C+L+P">L谩szl贸 P.

Simulation results agree with the experimental results reported in arXiv:2007.14894v2: with negative gradients, the charge of the modulated bunch is lower than with positive gradients. In addition, the bunch modulation frequency varies with gradient. Simulation results show that dephasing of the wakefields with respect to the relativistic protons along the plasma is the main cause for the loss of charge. The study of the modulation frequency reveals details about the evolution of the self-modulation process along the plasma. In particular for negative gradients, the modulation frequency across time-resolved images of the bunch indicates the position along the plasma where protons leave the wakefields. Simulations and experimental results are in excellent agreement. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2107.11369v1-abstract-full').style.display = 'none'; document.getElementById('2107.11369v1-abstract-short').style.display = 'inline';">&#9651; Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 23 July, 2021; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> July 2021. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">13 pages, 11 figures</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Phys.

The central wavelength of the laser is resonant with the $D_2$ line of rubidium and the peak intensity in the $10^{12}-10^{14} ~W/cm^2$ range, enough to create a plasma channel with single electron ionization. We observe the absorption of the laser pulse for low energy, a regime of transverse confinement of the laser beam by the strong resonant nonlinearity for higher energies and the transverse broadening of the output beam when the nonlinearity is saturated due to full medium ionization. We compare experimental observations of transmitted pulse energy and transverse fluence profile with the results of computer simulations modeling pulse propagation. We find a qualitative agreement between theory and experiment that corroborates the validity of our propagation model. While the quantitative differences are substantial, the results show that the model can be used to interpret the observed phenomena in terms of self-focusing and channeling of the laser pulses by the saturable nonlinearity and the transparency of the fully ionized medium along the propagation axis. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2103.14530v2-abstract-full').style.display = 'none'; document.getElementById('2103.14530v2-abstract-short').style.display = 'inline';">&#9651; Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 20 September, 2021; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 26 March, 2021; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> March 2021. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">12 pages, 10 Figures</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Phys.

The development of the longitudinal wakefield amplitude driven by a self-modulated proton bunch is measured using the external injection of witness electrons that sample the fields. In simulation, resonant excitation of the wakefield causes plasma electron trajectory crossing, resulting in the development of a potential outside the plasma boundary as electrons are transversely ejected.

The standard way to achieve full ionization is to use high power laser which can assure the over-barrier-ionization (OBI) along the 10 meters long active region. The Wigner-team in Budapest is investigating an alternative way of uniform plasma generation. The proposed Resonance Enhanced Multi Photon Ionization (REMPI) scheme probably can be realized by much less laser power. In the following the resonant pre-excitations of the Rb atoms are investigated, theoretically and the status report about the preparatory work on the experiment are presented. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1309.2442v1-abstract-full').style.display = 'none'; document.getElementById('1309.2442v1-abstract-short').style.display = 'inline';">&#9651; Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 10 September, 2013; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> September 2013. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">8 pages, 6 figures, submitted to Nucl.
