adding a qubit to a black hole requires energy $\Delta E \geq T_H \log 2$ so that the extra Bekenstein-Hawking entropy can accommodate the qubit. In this essay, we explain how the recently discovered phenomenon of black hole decoherence allows quantum information to be teleported into a black hole, with arbitrarily small energy cost. The generalized second law is not violated and there is no conflict with unitarity because the teleportation creates new entanglement, analogous to Hawking radiation, between the black hole interior and exterior. In accordance with Landauer's principle, a nonzero minimum energy cost only appears when there is a net erasure of information and noise from the exterior or, equivalently, when ``zerobits'' are sent into the black hole. </p> </div> </dd> <dt> <a name='item2'>[2]</a> <a href ="/abs/2504.01066" title="Abstract" id="2504.01066"> arXiv:2504.01066 </a> [<a href="/pdf/2504.01066" title="Download PDF" id="pdf-2504.01066" aria-labelledby="pdf-2504.01066">pdf</a>, <a href="https://arxiv.org/html/2504.01066v1" title="View HTML" id="html-2504.01066" aria-labelledby="html-2504.01066" rel="noopener noreferrer" target="_blank">html</a>, <a href="/format/2504.01066" title="Other formats" id="oth-2504.01066" aria-labelledby="oth-2504.01066">other</a>] </dt> <dd> <div class='meta'> <div class='list-title mathjax'><span class='descriptor'>Title:</span> Emergent Strings in Type IIB Calabi--Yau Compactifications </div> <div class='list-authors'><a href="https://arxiv.org/search/hep-th?searchtype=author&query=Friedrich,+B">Bjoern Friedrich</a>, <a href="https://arxiv.org/search/hep-th?searchtype=author&query=Monnee,+J">Jeroen Monnee</a>, <a href="https://arxiv.org/search/hep-th?searchtype=author&query=Weigand,+T">Timo Weigand</a>, <a href="https://arxiv.org/search/hep-th?searchtype=author&query=Wiesner,+M">Max Wiesner</a></div> <div class='list-comments mathjax'><span class='descriptor'>Comments:</span> 69 pages, 8 figures, 2 tables </div> <div class='list-subjects'><span class='descriptor'>Subjects:</span> <span class="primary-subject">High Energy Physics - Theory (hep-th)</span>; Algebraic Geometry (math.AG) </div> <p class='mathjax'> We study infinite distance limits in the complex structure moduli space of Type IIB compactifications on Calabi--Yau threefolds, in light of the Emergent String Conjecture. We focus on the so-called type II limits, which, based on the asymptotic behaviour of the physical couplings in the low-energy effective theory, are candidates for emergent string limits. However, due to the absence of Type IIB branes of suitable dimensionality, the emergence of a unique critical string accompanied by a tower of Kaluza--Klein states has so far remained elusive. By considering a broad class of type II$_b$ limits, corresponding to so-called Tyurin degenerations, and studying the asymptotic behaviour of four-dimensional EFT strings in this geometry, we argue that the worldsheet theory of the latter describes a unique critical heterotic string on $T^2\times\mathrm{K3}$ with a gauge bundle whose rank depends on $b$. In addition, we establish the presence of an infinite tower of BPS particles arising from wrapped D3-branes by identifying a suitable set of special Lagrangian 3-cycles in the geometry. The associated BPS invariants are conjectured to be counted by generalisations of modular forms. As a consistency check, we further show that in special cases mirror symmetry identifies the EFT strings with the well-understood emergent string limits in the K盲hler moduli space of Type IIA compactifications on K3-fibred Calabi--Yau threefolds. Finally, we discuss the implications of the Emergent String Conjecture for type II limits which do not correspond to Tyurin degenerations, and predict new constraints on the possible geometries of type II degenerations which resemble those arising in the Kulikov classification of degenerations of K3 surfaces. </p> </div> </dd> <dt> <a name='item3'>[3]</a> <a href ="/abs/2504.01088" title="Abstract" id="2504.01088"> arXiv:2504.01088 </a> [<a href="/pdf/2504.01088" title="Download PDF" id="pdf-2504.01088" aria-labelledby="pdf-2504.01088">pdf</a>, <a href="/format/2504.01088" title="Other formats" id="oth-2504.01088" aria-labelledby="oth-2504.01088">other</a>] </dt> <dd> <div class='meta'> <div class='list-title mathjax'><span class='descriptor'>Title:</span> Charting the Triality Webs for All Smooth Fano 3-Folds </div> <div class='list-authors'><a href="https://arxiv.org/search/hep-th?searchtype=author&query=Carcamo,+M">Mario Carcamo</a>, <a href="https://arxiv.org/search/hep-th?searchtype=author&query=Franco,+S">Sebasti谩n Franco</a></div> <div class='list-comments mathjax'><span class='descriptor'>Comments:</span> 96 pages, 41 figures </div> <div class='list-subjects'><span class='descriptor'>Subjects:</span> <span class="primary-subject">High Energy Physics - Theory (hep-th)</span> </div> <p class='mathjax'> We determine all toric phases for the $2d$ $(0,2)$ theories on D1-branes probing the complex cones over the 18 smooth Fano 3-folds, whose toric diagrams correspond to the regular reflexive polytopes in 3 dimensions.

Two small quantities, $\alpha$ and $\lambda$, corresponding to standard slow-roll parameters are defined and systematic expansions of all inflationary quantities in terms of powers of $\alpha$ and $\lambda$ are found. No other slow-roll parameters are needed. To illustrate this perturbative method in the multi-field context, we adopt a simple two-inflaton model with quadratic potentials in the parameter range where both fields contribute similarly to the dynamics of inflation. The model, even though it is not a viable alternative for phenomenological description of the inflationary period, nicely illustrates subtleties of the perturbative approach. In particular, this method allows us to derive two independent gauge-invariant scalar perturbations that are conserved in the superhorizon limit, overcoming typical problems that emerge in multi-field inflation. Furthermore, it is possible to perform nonperturbative resummations that allow to study the model in a true multi-field regime. We derive tensor and scalar power spectra to the next-to-next-to-leading and next-to-leading orders, respectively, as well as their spectral indices. The hierarchy between the two scalar perturbations allows us to single out the dominant entry of the scalar power-spectrum matrix. Modifications due to the second inflaton occur already at the leading order. Finally, we explain why the quadratic two-inflaton model is not compatible with the present experimental constraints even though non-trivial corrections to scalar perturbations do emerge. </p> </div> </dd> <dt> <a name='item7'>[7]</a> <a href ="/abs/2504.01177" title="Abstract" id="2504.01177"> arXiv:2504.01177 </a> [<a href="/pdf/2504.01177" title="Download PDF" id="pdf-2504.01177" aria-labelledby="pdf-2504.01177">pdf</a>, <a href="https://arxiv.org/html/2504.01177v1" title="View HTML" id="html-2504.01177" aria-labelledby="html-2504.01177" rel="noopener noreferrer" target="_blank">html</a>, <a href="/format/2504.01177" title="Other formats" id="oth-2504.01177" aria-labelledby="oth-2504.01177">other</a>] </dt> <dd> <div class='meta'> <div class='list-title mathjax'><span class='descriptor'>Title:</span> New intertwining operators for the Calogero model </div> <div class='list-authors'><a href="https://arxiv.org/search/hep-th?searchtype=author&query=Correa,+F">Francisco Correa</a>, <a href="https://arxiv.org/search/hep-th?searchtype=author&query=Inzunza,+L">Luis Inzunza</a>, <a href="https://arxiv.org/search/hep-th?searchtype=author&query=Lechtenfeld,+O">Olaf Lechtenfeld</a></div> <div class='list-subjects'><span class='descriptor'>Subjects:</span> <span class="primary-subject">High Energy Physics - Theory (hep-th)</span>; Mathematical Physics (math-ph); Exactly Solvable and Integrable Systems (nlin.SI); Quantum Physics (quant-ph) </div> <p class='mathjax'> It is long known that quantum Calogero models feature intertwining operators, which increase or decrease the coupling constant by an integer amount, for any fixed number of particles. We name these as ``horizontal'' and construct new ``vertical'' intertwiners, which \emph{change the number of interacting particles} for a fixed but integer value of the coupling constant. The emerging new structure of a grid of intertwiners exists only in the algebraically integrable situation (integer coupling) and allows one to obtain each Liouville charge from the free power sum in the particle momenta by iterated intertwining either horizontally or vertically. We present recursion formul忙 for the new intertwiners as a factorization problem for partial differential operators and prove their existence for small values of particle number and coupling. As a byproduct, a new basis of non-symmetric Liouville integrals appears, algebraically related to the standard symmetric one. </p> </div> </dd> <dt> <a name='item8'>[8]</a> <a href ="/abs/2504.01179" title="Abstract" id="2504.01179"> arXiv:2504.01179 </a> [<a href="/pdf/2504.01179" title="Download PDF" id="pdf-2504.01179" aria-labelledby="pdf-2504.01179">pdf</a>, <a href="https://arxiv.org/html/2504.01179v1" title="View HTML" id="html-2504.01179" aria-labelledby="html-2504.01179" rel="noopener noreferrer" target="_blank">html</a>, <a href="/format/2504.01179" title="Other formats" id="oth-2504.01179" aria-labelledby="oth-2504.01179">other</a>] </dt> <dd> <div class='meta'> <div class='list-title mathjax'><span class='descriptor'>Title:</span> Feshbach-Villars Formalism for a Spin-1/2 Particle in Curved Spacetime </div> <div class='list-authors'><a href="https://arxiv.org/search/hep-th?searchtype=author&query=Boumali,+A">Abdelmalek Boumali</a></div> <div class='list-subjects'><span class='descriptor'>Subjects:</span> <span class="primary-subject">High Energy Physics - Theory (hep-th)</span> </div> <p class='mathjax'> This study explores the Feshbach-Villars (FV) formalism for spin-1/2 particles in curved spacetime.

However, if the K盲hler potential respects the SL$(2, \mathbb{Z})$ (Sp$(2(h^{2,1}+1))$) symmetry of the axio-dilaton (complex structure moduli) even at the quantum level, the corrected K盲hler potential generated by the coupling of the dilaton (complex structure moduli) to some lattice structure may diverge in the large field limit, resulting in the lost of the perturbative control. As can be found in the explicitly calculable models, such a divergence may not be affected by the symmetry breaking by, for example, the gauge fields in the brane. This sets the upper bounds on the field values of the dilaton and the complex structure moduli determined by the volume of the internal manifold and the string coupling constant, hence the Kaluza-Klein and the string mass scales. The form and the interpretation of these bounds are quite similar to those of the distance conjecture, preventing the descent of a tower of states by the upper bounds on the moduli values. </p> </div> </dd> <dt> <a name='item10'>[10]</a> <a href ="/abs/2504.01286" title="Abstract" id="2504.01286"> arXiv:2504.01286 </a> [<a href="/pdf/2504.01286" title="Download PDF" id="pdf-2504.01286" aria-labelledby="pdf-2504.01286">pdf</a>, <a href="https://arxiv.org/html/2504.01286v1" title="View HTML" id="html-2504.01286" aria-labelledby="html-2504.01286" rel="noopener noreferrer" target="_blank">html</a>, <a href="/format/2504.01286" title="Other formats" id="oth-2504.01286" aria-labelledby="oth-2504.01286">other</a>] </dt> <dd> <div class='meta'> <div class='list-title mathjax'><span class='descriptor'>Title:</span> Graviton Scattering on Gravitational Atoms: Relic Graviton Shot Noise </div> <div class='list-authors'><a href="https://arxiv.org/search/hep-th?searchtype=author&query=Avila-Lopez,+B">Benjamin Avila-Lopez</a>, <a href="https://arxiv.org/search/hep-th?searchtype=author&query=MacKenzie,+R">Richard MacKenzie</a>, <a href="https://arxiv.org/search/hep-th?searchtype=author&query=Mendez,+F">Fernando Mendez</a>, <a href="https://arxiv.org/search/hep-th?searchtype=author&query=Paranjape,+M+B">M.

The distance is measured by a metric that is derived by taking an off-shell quadratic variation of the effective action, and evaluating it over families of vacua. We calculate this metric for increasingly complex families of vacua. We first consider the two-parameter families of solutions of type $\mathrm{AdS}_4 \times \mathbb{C}\mathrm{P}^3$. We find that the metric is flat and positive, and so yields a well-defined distance along any path in the space of solutions. We then consider solutions of type $\mathrm{AdS}_3 \times S^3 \times \mathrm{CY}_2$ which have two (non-compact) flux parameters as well as a moduli space. We find that the space of solutions factorises between directions which vary the AdS radius, and the moduli space. The metric over AdS variations is flat and positive, and the metric over the moduli space is the usual one. Finally, we consider solutions of type $\mathrm{AdS}_3 \times S^3 \times S^3 \times S^1$ which also have a further direction in the space of solutions that is compact. We find that the metric is flat only on non-compact directions in the space of solutions. Restricting to such directions, we evaluate the metric and find it is positive definite and therefore yields a well-defined distance along any path. </p> </div> </dd> <dt> <a name='item12'>[12]</a> <a href ="/abs/2504.01340" title="Abstract" id="2504.01340"> arXiv:2504.01340 </a> [<a href="/pdf/2504.01340" title="Download PDF" id="pdf-2504.01340" aria-labelledby="pdf-2504.01340">pdf</a>, <a href="https://arxiv.org/html/2504.01340v1" title="View HTML" id="html-2504.01340" aria-labelledby="html-2504.01340" rel="noopener noreferrer" target="_blank">html</a>, <a href="/format/2504.01340" title="Other formats" id="oth-2504.01340" aria-labelledby="oth-2504.01340">other</a>] </dt> <dd> <div class='meta'> <div class='list-title mathjax'><span class='descriptor'>Title:</span> Local conformal symmetry and anomalies with antisymmetric tensor field </div> <div class='list-authors'><a href="https://arxiv.org/search/hep-th?searchtype=author&query=Shapiro,+I+L">Ilya L.

For odd $p$, such theories possess $\mathsf{U}(1)$ duality invariance and include the Born-Infeld and ModMax theories. For even $p$, they describe a self-interacting chiral $p$-form with its gauge-invariant field strength obeying a nonlinear self-duality condition. We provide a complete description of $T\bar T$-like deformations of $\mathsf{U}(1)$ duality-invariant models for nonlinear electrodynamics in four dimensions and their six-dimensional counterparts -- interacting chiral two-form field theories.

This process of `contact reduction' leads to theories of a frictional nature, in which the physically-observable quantities form an autonomous subsystem, that evolves in a predictable manner. We demonstrate that this procedure has a natural generalisation to theories of higher order; detailed examples are provided, and physical implications discussed. </p> </div> </dd> <dt> <a name='item20'>[20]</a> <a href ="/abs/2504.01078" title="Abstract" id="2504.01078"> arXiv:2504.01078 </a> (cross-list from astro-ph.CO) [<a href="/pdf/2504.01078" title="Download PDF" id="pdf-2504.01078" aria-labelledby="pdf-2504.01078">pdf</a>, <a href="/format/2504.01078" title="Other formats" id="oth-2504.01078" aria-labelledby="oth-2504.01078">other</a>] </dt> <dd> <div class='meta'> <div class='list-title mathjax'><span class='descriptor'>Title:</span> Bootstrapping LSS perturbation theory beyond third order </div> <div class='list-authors'><a href="https://arxiv.org/search/astro-ph?searchtype=author&query=Ansari,+A">Arhum Ansari</a>, <a href="https://arxiv.org/search/astro-ph?searchtype=author&query=Banerjee,+A">Arka Banerjee</a>, <a href="https://arxiv.org/search/astro-ph?searchtype=author&query=Jain,+S">Sachin Jain</a>, <a href="https://arxiv.org/search/astro-ph?searchtype=author&query=Lalsodagar,+S">Sahil Lalsodagar</a></div> <div class='list-comments mathjax'><span class='descriptor'>Comments:</span> 24+7 pages, 3 appendices </div> <div class='list-subjects'><span class='descriptor'>Subjects:</span> <span class="primary-subject">Cosmology and Nongalactic Astrophysics (astro-ph.CO)</span>; High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th) </div> <p class='mathjax'> Bootstrap techniques relying on the constraints imposed by Extended Galilean Invariance (EGI), have proved to be very useful in the context of perturbation theory of the Large Scale Structure (LSS). It has been formulated in both the Eulerian as well as Lagrangian space. While the Eulerian bootstrap formalism has been successfully applied to both tracer and matter kernels, the application of bootstrap methods in Lagrangian space has so far been restricted to matter. Up to third order, it has been shown that implementing EGI constraints in Eulerian space fully reproduces the bias expansion for tracers. Previous studies have demonstrated that time non-locality affects the bias expansion in a non-trivial way starting from fifth order. Motivated by this fact, we extend the bootstrap approach upto fifth order in both Eulerian and Lagrangian space and demonstrate that it fully captures the time non-local effects. For this, we generalize the Lagrangian bootstrap for tracers, and found that it agrees with the corresponding results obtained in Eulerian space. One of the major challenges in implementing EGI constraints in Eulerian space, is to systematically find out all the "spurious poles" and make them vanish. We have proposed a method that bypasses this difficulty making the procedure tractable at higher orders. From Lagrangian perspective, we have identified coefficients in the tracer kernel whose ratios are independent of tracer properties and may serve as direct probes of the underlying cosmology. </p> </div> </dd> <dt> <a name='item21'>[21]</a> <a href ="/abs/2504.01080" title="Abstract" id="2504.01080"> arXiv:2504.01080 </a> (cross-list from cond-mat.str-el) [<a href="/pdf/2504.01080" title="Download PDF" id="pdf-2504.01080" aria-labelledby="pdf-2504.01080">pdf</a>, <a href="https://arxiv.org/html/2504.01080v1" title="View HTML" id="html-2504.01080" aria-labelledby="html-2504.01080" rel="noopener noreferrer" target="_blank">html</a>, <a href="/format/2504.01080" title="Other formats" id="oth-2504.01080" aria-labelledby="oth-2504.01080">other</a>] </dt> <dd> <div class='meta'> <div class='list-title mathjax'><span class='descriptor'>Title:</span> Chiral vortex-line liquid of three-dimensional interacting Bose systems with moat dispersion </div> <div class='list-authors'><a href="https://arxiv.org/search/cond-mat?searchtype=author&query=Jafari-Zadeh,+B">Bahar Jafari-Zadeh</a>, <a href="https://arxiv.org/search/cond-mat?searchtype=author&query=Wei,+C">Chenan Wei</a>, <a href="https://arxiv.org/search/cond-mat?searchtype=author&query=Sedrakyan,+T+A">Tigran A.

By extending the two-dimensional Chern-Simons flux-attachment transformation to three dimensions through a combination of planar CS phases and Jordan-Wigner fermionization along vortex lines, we construct the CVLL state, characterized by nontrivial vortex-line excitations with topological properties. We develop an associated topological field theory in a curved spatial geometry and study the low-energy effective theory of the CVLL state. Using Monte Carlo simulations, we numerically determine the CVLL ground state's chemical potential for interacting bosons in cylindrical moat-band geometries and demonstrate that the CVLL phase energetically outcompetes traditional condensate phases at low densities, highlighting its relevance to experimental platforms including frustrated quantum magnets, ultracold atomic gases, physics of rotons in $^4$He, and moat regimes in heavy-ion collisions. </p> </div> </dd> <dt> <a name='item22'>[22]</a> <a href ="/abs/2504.01224" title="Abstract" id="2504.01224"> arXiv:2504.01224 </a> (cross-list from gr-qc) [<a href="/pdf/2504.01224" title="Download PDF" id="pdf-2504.01224" aria-labelledby="pdf-2504.01224">pdf</a>, <a href="https://arxiv.org/html/2504.01224v1" title="View HTML" id="html-2504.01224" aria-labelledby="html-2504.01224" rel="noopener noreferrer" target="_blank">html</a>, <a href="/format/2504.01224" title="Other formats" id="oth-2504.01224" aria-labelledby="oth-2504.01224">other</a>] </dt> <dd> <div class='meta'> <div class='list-title mathjax'><span class='descriptor'>Title:</span> On the bouncing completion of eternal inflation </div> <div class='list-authors'><a href="https://arxiv.org/search/gr-qc?searchtype=author&query=Ferreira,+A+L">Alexsandre L.

Recently, discussions about the broadness of this theorem have been resurfaced by applying it to new models and/or challenging the space-time maximality hypothesis. In the present work, we use reference frames of non co-moving observers and their kinematical properties in order to inquire into the nature of such possible singular beginnings. Using the spatially flat de Sitter (dS) space-time as a laboratory, this approach allows us to exhaust all possibilities bounded by the BGV theorem in the case of general spatially flat Friedmann-Lema\^谋tre-Robertson-Walker (FLRW) geometries. We show that either there exists a scalar or parallelly propagated curvature singularity, or the space-time must be past asymptotically dS (with a definite non-zero limit of the Hubble parameter when the scale factor becomes null, hence excluding certain cyclic models) in order to be extensible. We are able to present this local extension without violating the null energy condition, and we show that this extension must contain a bounce. This is a mathematical result based on purely kinematical arguments and intuition. The possible physical realization of such extensions are also discussed. As a side product, we present a new chart that covers all de Sitter space-time. </p> </div> </dd> <dt> <a name='item23'>[23]</a> <a href ="/abs/2504.01539" title="Abstract" id="2504.01539"> arXiv:2504.01539 </a> (cross-list from gr-qc) [<a href="/pdf/2504.01539" title="Download PDF" id="pdf-2504.01539" aria-labelledby="pdf-2504.01539">pdf</a>, <a href="https://arxiv.org/html/2504.01539v1" title="View HTML" id="html-2504.01539" aria-labelledby="html-2504.01539" rel="noopener noreferrer" target="_blank">html</a>, <a href="/format/2504.01539" title="Other formats" id="oth-2504.01539" aria-labelledby="oth-2504.01539">other</a>] </dt> <dd> <div class='meta'> <div class='list-title mathjax'><span class='descriptor'>Title:</span> Black hole solutions in quantum phenomenological gravitational dynamics </div> <div class='list-authors'><a href="https://arxiv.org/search/gr-qc?searchtype=author&query=Alonso-Serrano,+A">Ana Alonso-Serrano</a>, <a href="https://arxiv.org/search/gr-qc?searchtype=author&query=de+Cesare,+M">Marco de Cesare</a>, <a href="https://arxiv.org/search/gr-qc?searchtype=author&query=Del+Piano,+M">Manuel Del Piano</a></div> <div class='list-comments mathjax'><span class='descriptor'>Comments:</span> 9 pages </div> <div class='list-subjects'><span class='descriptor'>Subjects:</span> <span class="primary-subject">General Relativity and Quantum Cosmology (gr-qc)</span>; High Energy Physics - Theory (hep-th) </div> <p class='mathjax'> We investigate black hole solutions within a phenomenological approach to quantum gravity based on spacetime thermodynamics developed by Alonso-Serrano and Li拧ka.

In this work, we extend our investigation to the $\gamma^{(*)} + N(940)\frac{1}{2}^+ \to N(1520)\frac{3}{2}^{-}$ transition. Our computed transition form factors show reasonable agreement with experimental data at large photon virtualities. However, deviations emerge at low $Q^2$, where experimental results exhibit a sharper variation than theoretical predictions. This discrepancy is expected, as these continuum QCD analyses account only for the quark-core of baryons, while low photon virtualities are dominated by meson cloud effects. We anticipate that these analytical predictions, based on the simplified SCI framework, will serve as a valuable benchmark for more refined studies and QCD-based truncations that incorporate quark angular momentum and the contributions of scalar and vector diquarks. </p> </div> </dd> <dt> <a name='item31'>[31]</a> <a href ="/abs/2504.01814" title="Abstract" id="2504.01814"> arXiv:2504.01814 </a> (cross-list from nucl-th) [<a href="/pdf/2504.01814" title="Download PDF" id="pdf-2504.01814" aria-labelledby="pdf-2504.01814">pdf</a>, <a href="https://arxiv.org/html/2504.01814v1" title="View HTML" id="html-2504.01814" aria-labelledby="html-2504.01814" rel="noopener noreferrer" target="_blank">html</a>, <a href="/format/2504.01814" title="Other formats" id="oth-2504.01814" aria-labelledby="oth-2504.01814">other</a>] </dt> <dd> <div class='meta'> <div class='list-title mathjax'><span class='descriptor'>Title:</span> Energy Density Functional of Confined Quarks: an Improved Ansatz </div> <div class='list-authors'><a href="https://arxiv.org/search/nucl-th?searchtype=author&query=Shukla,+U">Udita Shukla</a>, <a href="https://arxiv.org/search/nucl-th?searchtype=author&query=Lo,+P+M">Pok Man Lo</a></div> <div class='list-comments mathjax'><span class='descriptor'>Comments:</span> submitted to JSPC </div> <div class='list-subjects'><span class='descriptor'>Subjects:</span> <span class="primary-subject">Nuclear Theory (nucl-th)</span>; High Energy Astrophysical Phenomena (astro-ph.HE); High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th) </div> <p class='mathjax'> Density Functional Theory (DFT) is a robust framework for modeling interacting many-body systems, including the equation of state (EoS) of dense matter. Many models, however, rely on energy functionals based on assumptions that have not been rigorously validated. We critically analyze a commonly used ansatz for confinement, where the energy functional scales with density as $U \propto n^{\frac{2}{3}}$ . Our findings, derived from a systematic non-local energy functional, reveal that this scaling does not capture the dynamics of confinement. Instead, the energy functional evolves from $n^2$ at low densities to $n$ at high densities, governed by an infrared cutoff. These results suggest that models relying on such assumptions should be revisited to ensure more reliable EoS construction. </p> </div> </dd> <dt> <a name='item32'>[32]</a> <a href ="/abs/2504.01830" title="Abstract" id="2504.01830"> arXiv:2504.01830 </a> (cross-list from astro-ph.HE) [<a href="/pdf/2504.01830" title="Download PDF" id="pdf-2504.01830" aria-labelledby="pdf-2504.01830">pdf</a>, <a href="https://arxiv.org/html/2504.01830v1" title="View HTML" id="html-2504.01830" aria-labelledby="html-2504.01830" rel="noopener noreferrer" target="_blank">html</a>, <a href="/format/2504.01830" title="Other formats" id="oth-2504.01830" aria-labelledby="oth-2504.01830">other</a>] </dt> <dd> <div class='meta'> <div class='list-title mathjax'><span class='descriptor'>Title:</span> Is Lorentz invariance violation found? </div> <div class='list-authors'><a href="https://arxiv.org/search/astro-ph?searchtype=author&query=Galanti,+G">Giorgio Galanti</a>, <a href="https://arxiv.org/search/astro-ph?searchtype=author&query=Roncadelli,+M">Marco Roncadelli</a>, <a href="https://arxiv.org/search/astro-ph?searchtype=author&query=Tavecchio,+F">Fabrizio Tavecchio</a></div> <div class='list-comments mathjax'><span class='descriptor'>Comments:</span> 7 pages, 2 figures </div> <div class='list-subjects'><span class='descriptor'>Subjects:</span> <span class="primary-subject">High Energy Astrophysical Phenomena (astro-ph.HE)</span>; General Relativity and Quantum Cosmology (gr-qc); High Energy Physics - Phenomenology (hep-ph); High Energy Physics - Theory (hep-th) </div> <p class='mathjax'> Lorentz invariance violation (LIV) has long been recognized as an observable low-energy signature of quantum gravity. In spite of a great effort to detect LIV effects, so far only lower bounds have been derived. The high energy photons from the gamma ray burst GRB 221009A have been detected by the LHAASO collaboration and one at ${\cal E} \simeq 251 \, \rm TeV$ by the Carpet collaboration using a partial data set. Very recently, the Carpet collaboration has completed the full data analysis, reporting further support for their previously detected photon now at ${\cal E} = 300^{+ 43}_{- 38} \, {\rm TeV}$, which manifestly clashes with conventional physics. Taking this result at face value, we derive the first evidence for LIV and we show that such a detection cannot be explained by axion-like particles (ALPs), which allow for the observation of the highest energy photons detected by LHAASO. We also outline a scenario in which ALPs and LIV naturally coexist. If confirmed by future observations our finding would represent the first positive result in quantum gravity phenomenology. </p> </div> </dd> <dt> <a name='item33'>[33]</a> <a href ="/abs/2504.01904" title="Abstract" id="2504.01904"> arXiv:2504.01904 </a> (cross-list from hep-ph) [<a href="/pdf/2504.01904" title="Download PDF" id="pdf-2504.01904" aria-labelledby="pdf-2504.01904">pdf</a>, <a href="https://arxiv.org/html/2504.01904v1" title="View HTML" id="html-2504.01904" aria-labelledby="html-2504.01904" rel="noopener noreferrer" target="_blank">html</a>, <a href="/format/2504.01904" title="Other formats" id="oth-2504.01904" aria-labelledby="oth-2504.01904">other</a>] </dt> <dd> <div class='meta'> <div class='list-title mathjax'><span class='descriptor'>Title:</span> A Dilaton Sum Rule for the Conformal Anomaly Form Factor in QCD at Order $伪_s$ </div> <div class='list-authors'><a href="https://arxiv.org/search/hep-ph?searchtype=author&query=Corian%C3%B2,+C">Claudio Corian貌</a>, <a href="https://arxiv.org/search/hep-ph?searchtype=author&query=Lionetti,+S">Stefano Lionetti</a>, <a href="https://arxiv.org/search/hep-ph?searchtype=author&query=Melle,+D">Dario Melle</a>, <a href="https://arxiv.org/search/hep-ph?searchtype=author&query=Torcellini,+L">Leonardo Torcellini</a></div> <div class='list-comments mathjax'><span class='descriptor'>Comments:</span> 37 pages, 3 figures </div> <div class='list-subjects'><span class='descriptor'>Subjects:</span> <span class="primary-subject">High Energy Physics - Phenomenology (hep-ph)</span>; High Energy Physics - Theory (hep-th) </div> <p class='mathjax'> We present an off-shell dispersive analysis of the graviton-gluon-gluon $ TJJ $ vertex, extending previous QED and QCD results of this interaction, and show that it satisfies a conformal anomaly sum rule at one-loop, under the most general kinematical conditions. The conformal anomaly form factor emerges from the trace sector of the interaction and its absorptive amplitude is constrained by an area law similarly to the chiral and gravitational anomaly cases. Building on our previous analysis of those anomalies, we illustrate the patterns of cancelation between the localized and the continuum contributions to the spectral density of this form factor. As in the chiral/gravitational case, a spectral flow localizes the exchanged intermediate state at zero momentum transfer as the quark mass is sent to zero. The perturbative analysis indicates that sum rules are central dynamical features of anomaly interactions, and the coupling or the decoupling of the associated dilaton poles are correlated with the saturation of the sum rule either by a pole or by a dispersive cut. In the conformal and on-shell limit, the particle pole interaction describes a nonlocal S-matrix element entirely supported on the light-cone, with contribution both from the dilaton pole in the trace sector and from other sectors of the correlator, except for flavour number $n_f=3$ quarks $ u,d,s$, where only the dilaton pole in the trace sector appears. </p> </div> </dd> </dl> <dl id='articles'> <h3>Replacement submissions (showing 26 of 26 entries)</h3> <dt> <a name='item34'>[34]</a> <a href ="/abs/2306.04589" title="Abstract" id="2306.04589"> arXiv:2306.04589 </a> (replaced) [<a href="/pdf/2306.04589" title="Download PDF" id="pdf-2306.04589" aria-labelledby="pdf-2306.04589">pdf</a>, <a href="https://arxiv.org/html/2306.04589v2" title="View HTML" id="html-2306.04589" aria-labelledby="html-2306.04589" rel="noopener noreferrer" target="_blank">html</a>, <a href="/format/2306.04589" title="Other formats" id="oth-2306.04589" aria-labelledby="oth-2306.04589">other</a>] </dt> <dd> <div class='meta'> <div class='list-title mathjax'><span class='descriptor'>Title:</span> Unifying fractons, gravitons and photons from a gauge theoretical approach </div> <div class='list-authors'><a href="https://arxiv.org/search/hep-th?searchtype=author&query=Sobreiro,+R+F">Rodrigo F.

After discussing the most general quadratic action for this field, we explore the physical sectors contained in the model. Particularly, we show that the model contains not only linear gravity and fractons, but also ordinary Maxwell equations, suggesting an apparent electrically charged phase of, for instance, spin liquids and glassy dynamical systems.

This is achieved by analyzing the perturbative back reaction of the quantum confined particle's eigenstates and spectra upon the geometry of the curved surface itself, thereby addressing the problem of shape optimization in this model. We do this by first formulating a two-dimensional action principle of the quantum constrained particle, which upon variation of the wave function reproduces Schr枚dinger's equation including da Costa's surface curvature-induced potentials. We further demonstrate that our derived action principle is dual to a two-dimensional dilation gravity theory and we vary its functional with respect to the embedded two-dimensional inverse-metric to obtain the respective geometrodynamical Einstein equation. We solve this resulting Einstein equation perturbatively by first solving the da Costa's Schr枚dinger equation to obtain an initial eigensystem, which is used as initial-input data for a perturbed metric inserted into the derived Einstein equation. As a proof of concept, we perform this calculation on a two-sphere and show its first iterative perturbed shape evolution. We also turn on external electromagnetic fields and formulate the full field theoretic field equations for future investigation. The external fields manifest themselves via a surface induced, pulled-back $U(1)$ coupling in our two-dimensional dual gravity theory, thereby revealing interesting and rich new surface physics in this specific paradigm. </p> </div> </dd> <dt> <a name='item36'>[36]</a> <a href ="/abs/2405.20855" title="Abstract" id="2405.20855"> arXiv:2405.20855 </a> (replaced) [<a href="/pdf/2405.20855" title="Download PDF" id="pdf-2405.20855" aria-labelledby="pdf-2405.20855">pdf</a>, <a href="https://arxiv.org/html/2405.20855v2" title="View HTML" id="html-2405.20855" aria-labelledby="html-2405.20855" rel="noopener noreferrer" target="_blank">html</a>, <a href="/format/2405.20855" title="Other formats" id="oth-2405.20855" aria-labelledby="oth-2405.20855">other</a>] </dt> <dd> <div class='meta'> <div class='list-title mathjax'><span class='descriptor'>Title:</span> Modified Euler-Heisenberg effective action and Proper-Time Method in Lorentz-Violating Scalar QED </div> <div class='list-authors'><a href="https://arxiv.org/search/hep-th?searchtype=author&query=Brito,+L+C+T">L.

The spin-orbit duality is a holographic map that projects a massive theory in four-dimensional flat spacetime onto the three-dimensional $\mathbb{S}^2\times\mathbb{R}$ null infinity. This cylinder has radius $R\sim1/m$ and, quantum-mechanically, its vacuum state is a fuzzy sphere. Progress shows that, first, this duality realizes the Hopf map, a fact manifest on the superparticle. Secondly, the bulk Poincar猫 group transforms into the conformal group on the cylinder. In fact, the general version of the duality yields that the dual symmetries include the BMS group, as is appropriate at null infinity. As an example, the Landau levels in $\mathbb{R}^3$ are shown to match those of a Dirac monopole on the dual $\mathbb{S}^2$, in the thermodynamic limit. This dual system is actually identified with a three-dimensional critical Ising model. The map is then realized on $N_f$ massive fermions in flat space which, indeed, are the hologram of $2N_f$ massless fermions on the cylinder. However, the dual space is really the conformal class of $\mathbb{S}^2\times\mathbb{R}$, naturally enclosing the universal cover of a conformally compactified AdS$_4$ spacetime. We argue that, in the absence of interactions, the massless fermions on the conformal boundary are in turn dual to $N_f$ massive fermions in AdS$_4$. For free fermions, all path integrals $-$the ones in $\mathbb{R}^4$ and $\mathbb{S}^2\times\mathbb{R}$ and AdS$_4-$ are shown to match. Hence, AdS/CFT duality emerges into a larger context, where one holography nests inside the other, suggesting a complete holographic bridge between fields in flat space and the AdS superstring. </p> </div> </dd> <dt> <a name='item44'>[44]</a> <a href ="/abs/2501.09919" title="Abstract" id="2501.09919"> arXiv:2501.09919 </a> (replaced) [<a href="/pdf/2501.09919" title="Download PDF" id="pdf-2501.09919" aria-labelledby="pdf-2501.09919">pdf</a>, <a href="https://arxiv.org/html/2501.09919v2" title="View HTML" id="html-2501.09919" aria-labelledby="html-2501.09919" rel="noopener noreferrer" target="_blank">html</a>, <a href="/format/2501.09919" title="Other formats" id="oth-2501.09919" aria-labelledby="oth-2501.09919">other</a>] </dt> <dd> <div class='meta'> <div class='list-title mathjax'><span class='descriptor'>Title:</span> Quantum field theory on curved manifolds </div> <div class='list-authors'><a href="https://arxiv.org/search/hep-th?searchtype=author&query=Matsuda,+T">Tomohiro Matsuda</a></div> <div class='list-comments mathjax'><span class='descriptor'>Comments:</span> 35 pages, 6 figures, major update </div> <div class='list-subjects'><span class='descriptor'>Subjects:</span> <span class="primary-subject">High Energy Physics - Theory (hep-th)</span>; General Relativity and Quantum Cosmology (gr-qc); High Energy Physics - Phenomenology (hep-ph) </div> <p class='mathjax'> This paper discusses how particle production from the vacuum can be explained by local analysis when the field theory is defined by differential geometry on curved manifolds. We have performed the local analysis in a mathematically rigorous way, respecting the Markov property. The exact WKB is used as a tool for extracting non-perturbative effect from the local system. After a serious application of the differential geometry and the exact WKB to particle production, we show that entanglement does not appear in the Unruh effect as far as the standard formulation by the differential geometry is valid. This result should not be attributed to a consistency problem between the ``entanglement state'' and the ``standard field theory by differential geometry'', but to the fact that the conventional calculation of the Unruh effect is done by extrapolation which is not consistent with the differential geometry. The situation is similar to that of the Dirac monopole, but topology is not relevant and the basis for building field theories in differential geometry is strongly involved. </p> </div> </dd> <dt> <a name='item45'>[45]</a> <a href ="/abs/2503.10967" title="Abstract" id="2503.10967"> arXiv:2503.10967 </a> (replaced) [<a href="/pdf/2503.10967" title="Download PDF" id="pdf-2503.10967" aria-labelledby="pdf-2503.10967">pdf</a>, <a href="https://arxiv.org/html/2503.10967v2" title="View HTML" id="html-2503.10967" aria-labelledby="html-2503.10967" rel="noopener noreferrer" target="_blank">html</a>, <a href="/format/2503.10967" title="Other formats" id="oth-2503.10967" aria-labelledby="oth-2503.10967">other</a>] </dt> <dd> <div class='meta'> <div class='list-title mathjax'><span class='descriptor'>Title:</span> Supersymmetric Higher-Spin Gauge Theories in any $d$ and their Coupling Constants within BRST Formalism </div> <div class='list-authors'><a href="https://arxiv.org/search/hep-th?searchtype=author&query=Vasiliev,+M+A">M.

The presence of two massless fermions requires the Lowenstein-Zimmermann (LZ) subtraction scheme to renormalize the infrared divergences induced by the ultraviolet subtractions at 1- and 2-loops, moreover due to the model superrenormalizability the ultraviolet divergences are bounded up to 2-loops.

This framework separates the topological data from the local dynamics of a theory and provides a unified description of the symmetry and duality in gapped and gapless phases of matter. In this work, we develop the topological holographic picture for (1+1)d quantum phases, including both gapped phases as well as a wide range of quantum critical points, including phase transitions between symmetry protected topological (SPT) phases, symmetry enriched quantum critical points, deconfined quantum critical points, and intrinsically gapless SPT phases. Topological holography puts a strong constraint on the emergent symmetry and the anomaly for these critical theories. We show how the partition functions of these critical points can be obtained from dualizing (orbifolding) more familiar critical theories. The topological responses of the defect operators are also discussed in this framework. We further develop a topological holographic picture for conformal boundary states of (1+1)d rational conformal field theories. This framework provides a simple physical picture to understand conformal boundary states and also uncovers the nature of the gapped phases corresponding to the boundary states. </p> </div> </dd> <dt> <a name='item49'>[49]</a> <a href ="/abs/2311.15258" title="Abstract" id="2311.15258"> arXiv:2311.15258 </a> (replaced) [<a href="/pdf/2311.15258" title="Download PDF" id="pdf-2311.15258" aria-labelledby="pdf-2311.15258">pdf</a>, <a href="https://arxiv.org/html/2311.15258v3" title="View HTML" id="html-2311.15258" aria-labelledby="html-2311.15258" rel="noopener noreferrer" target="_blank">html</a>, <a href="/format/2311.15258" title="Other formats" id="oth-2311.15258" aria-labelledby="oth-2311.15258">other</a>] </dt> <dd> <div class='meta'> <div class='list-title mathjax'><span class='descriptor'>Title:</span> Non-perturbative quantum Yang--Mills at finite temperature beyond lattice: a Dyson--Schwinger approach </div> <div class='list-authors'><a href="https://arxiv.org/search/hep-ph?searchtype=author&query=Frasca,+M">Marco Frasca</a>, <a href="https://arxiv.org/search/hep-ph?searchtype=author&query=Ghoshal,+A">Anish Ghoshal</a>, <a href="https://arxiv.org/search/hep-ph?searchtype=author&query=Groote,+S">Stefan Groote</a></div> <div class='list-comments mathjax'><span class='descriptor'>Comments:</span> 25 pages, 4 figures </div> <div class='list-journal-ref'><span class='descriptor'>Journal-ref:</span> Symmetry 2025, 17(4), 543 </div> <div class='list-subjects'><span class='descriptor'>Subjects:</span> <span class="primary-subject">High Energy Physics - Phenomenology (hep-ph)</span>; General Relativity and Quantum Cosmology (gr-qc); High Energy Physics - Lattice (hep-lat); High Energy Physics - Theory (hep-th) </div> <p class='mathjax'> Using a Dyson--Schwinger approach, we perform an analysis of the non-trivial ground state of thermal $SU(N)$ Yang--Mills theory in the non-perturbative regime where chiral symmetry is dynamically broken by a mass gap. Basic thermodynamic observables such as energy density and pressure are derived analytically, using Jacobi elliptic functions. The results are compared with lattice results. Good agreement is found at low temperatures, providing a viable scenario of a gas of massive glue states populating higher levels of the spectrum of the theory. At high temperatures a scenario without glue states consistent with a massive scalar field is observed, showing an interesting agreement with lattice data.

Requirement of very high acceleration hinders its experimental evidence. We put forward an idea to experimentally probe this effect by utilizing the Pancharatnam-Berry phase of an accelerated atom in presence of mirrors. We show that for much lower accelerations, the phase gets significantly enhanced in the presence of mirrors. We propose a schematic design of an interferometric set-up to experimentally capture this effect by utilizing the phase difference between an accelerated and an inertial atoms.

Earlier work has shown that the computation of geodesic distance can be challenging for Lie groups relevant to harmonic oscillators. Here, this problem is approached by working to leading order in an expansion by the structure constants of the Lie group. An explicit formula for an upper bound on the quantum complexity of a harmonic oscillator Hamiltonian with time-dependent frequency is derived. Applied to a massless test scalar field on a cosmological de Sitter background, the upper bound on complexity as a function of the scale factor exhibits a logarithmic increase on super-Hubble scales. This result aligns with the gate complexity and earlier studies of de Sitter complexity. It demonstrates the consistent application of Nielsen complexity to quantum fields in cosmological backgrounds and paves the way for further applications. </p> </div> </dd> <dt> <a name='item52'>[52]</a> <a href ="/abs/2408.05919" title="Abstract" id="2408.05919"> arXiv:2408.05919 </a> (replaced) [<a href="/pdf/2408.05919" title="Download PDF" id="pdf-2408.05919" aria-labelledby="pdf-2408.05919">pdf</a>, <a href="/format/2408.05919" title="Other formats" id="oth-2408.05919" aria-labelledby="oth-2408.05919">other</a>] </dt> <dd> <div class='meta'> <div class='list-title mathjax'><span class='descriptor'>Title:</span> Guiding-centre Lagrangian and quasi-symmetry </div> <div class='list-authors'><a href="https://arxiv.org/search/physics?searchtype=author&query=Jacobson,+T">Ted Jacobson</a></div> <div class='list-comments mathjax'><span class='descriptor'>Comments:</span> v2: 14 pages, substantially edited for clarity, discussion and references to the literature on quasi-symmetry and its stellarator design applications added, section on existence of flux surfaces added, title spelling changed, published version </div> <div class='list-subjects'><span class='descriptor'>Subjects:</span> <span class="primary-subject">Plasma Physics (physics.plasm-ph)</span>; High Energy Physics - Theory (hep-th); Mathematical Physics (math-ph); Geophysics (physics.geo-ph) </div> <p class='mathjax'> A charged particle in a suitably strong magnetic field spirals along the field lines while slowly drifting transversely.

Earlier, we had examined inflationary magnetogenesis - achieved by breaking the conformal invariance of the electromagnetic action through a coupling to the inflaton - in situations involving departures from slow roll. We had found that a transition from slow roll to ultra slow roll inflation can lead to a strong blue tilt in the spectrum of the magnetic field over small scales and also considerably suppress its strength over large scales. In this work, we consider the scenario of pure ultra slow roll inflation and show that scale invariant magnetic fields can be obtained in such situations with the aid of a non-conformal coupling function that depends on the kinetic energy of the inflaton. Apart from the power spectrum, an important probe of the primordial magnetic fields are the three-point functions, specifically, the cross-correlation between the curvature perturbations and the magnetic fields. We calculate the three-point cross-correlation between the curvature perturbations and the magnetic fields in pure ultra slow roll inflation for the new choice of the non-conformal coupling function. In particular, we examine the validity of the consistency condition that is expected to govern the three-point function in the squeezed limit and comment on the wider implications of the results we obtain. </p> </div> </dd> <dt> <a name='item54'>[54]</a> <a href ="/abs/2410.23384" title="Abstract" id="2410.23384"> arXiv:2410.23384 </a> (replaced) [<a href="/pdf/2410.23384" title="Download PDF" id="pdf-2410.23384" aria-labelledby="pdf-2410.23384">pdf</a>, <a href="https://arxiv.org/html/2410.23384v2" title="View HTML" id="html-2410.23384" aria-labelledby="html-2410.23384" rel="noopener noreferrer" target="_blank">html</a>, <a href="/format/2410.23384" title="Other formats" id="oth-2410.23384" aria-labelledby="oth-2410.23384">other</a>] </dt> <dd> <div class='meta'> <div class='list-title mathjax'><span class='descriptor'>Title:</span> Gravitational Polarizability of Schwarzschild Black Holes </div> <div class='list-authors'><a href="https://arxiv.org/search/gr-qc?searchtype=author&query=Vidal,+G">Gabriel Vidal</a>, <a href="https://arxiv.org/search/gr-qc?searchtype=author&query=Dantas,+G+M">Gabriel M.

We review and combine results obtained via the Regge-Wheeler equation on one side and a perturbative, worldline effective field theory description on the other, obtaining a consistent description of the dispersion relations for the gravitational polarizability of a Schwarzschild black hole. We find that the classical part of the 2-point correlation function of the black hole multipole depends on the boundary conditions of the space-time the black hole is immersed in, which is relevant for the dispersion relations considered. </p> </div> </dd> <dt> <a name='item55'>[55]</a> <a href ="/abs/2412.19383" title="Abstract" id="2412.19383"> arXiv:2412.19383 </a> (replaced) [<a href="/pdf/2412.19383" title="Download PDF" id="pdf-2412.19383" aria-labelledby="pdf-2412.19383">pdf</a>, <a href="https://arxiv.org/html/2412.19383v3" title="View HTML" id="html-2412.19383" aria-labelledby="html-2412.19383" rel="noopener noreferrer" target="_blank">html</a>, <a href="/format/2412.19383" title="Other formats" id="oth-2412.19383" aria-labelledby="oth-2412.19383">other</a>] </dt> <dd> <div class='meta'> <div class='list-title mathjax'><span class='descriptor'>Title:</span> On the Quantum K-theory of Quiver Varieties at Roots of Unity </div> <div class='list-authors'><a href="https://arxiv.org/search/math?searchtype=author&query=Koroteev,+P">Peter Koroteev</a>, <a href="https://arxiv.org/search/math?searchtype=author&query=Smirnov,+A">Andrey Smirnov</a></div> <div class='list-comments mathjax'><span class='descriptor'>Comments:</span> 20 pages, minor corrections </div> <div class='list-subjects'><span class='descriptor'>Subjects:</span> <span class="primary-subject">Algebraic Geometry (math.AG)</span>; High Energy Physics - Theory (hep-th); Mathematical Physics (math-ph); Number Theory (math.NT); Representation Theory (math.RT) </div> <p class='mathjax'> Let $\Psi(\textbf{z},\textbf{a},q)$ a the fundamental solution matrix of the quantum difference equation of a Nakajima variety $X$.

Since the Hamiltonian under the Majorana mass term does not conserve lepton number, the eigenstates of lepton number change continuously over time. Therefore, the transition amplitude is described by the inner product of the eigenstates of lepton number at the time of the neutrino production and the detection. With the Bogoliubov transformation, we successfully relates the lepton number eigenstates at different times. This method enables us to understand the time variation of lepton number induced by chiral oscillations in terms of transition probabilities. We also present the physical picture that emerges through the Bogoliubov transformation. </p> </div> </dd> <dt> <a name='item57'>[57]</a> <a href ="/abs/2501.07490" title="Abstract" id="2501.07490"> arXiv:2501.07490 </a> (replaced) [<a href="/pdf/2501.07490" title="Download PDF" id="pdf-2501.07490" aria-labelledby="pdf-2501.07490">pdf</a>, <a href="https://arxiv.org/html/2501.07490v2" title="View HTML" id="html-2501.07490" aria-labelledby="html-2501.07490" rel="noopener noreferrer" target="_blank">html</a>, <a href="/format/2501.07490" title="Other formats" id="oth-2501.07490" aria-labelledby="oth-2501.07490">other</a>] </dt> <dd> <div class='meta'> <div class='list-title mathjax'><span class='descriptor'>Title:</span> Rationalisation of multiple square roots in Feynman integrals </div> <div class='list-authors'><a href="https://arxiv.org/search/hep-ph?searchtype=author&query=Papathanasiou,+G">Georgios Papathanasiou</a>, <a href="https://arxiv.org/search/hep-ph?searchtype=author&query=Weinzierl,+S">Stefan Weinzierl</a>, <a href="https://arxiv.org/search/hep-ph?searchtype=author&query=Wu,+K">Konglong Wu</a>, <a href="https://arxiv.org/search/hep-ph?searchtype=author&query=Zhang,+Y">Yang Zhang</a></div> <div class='list-comments mathjax'><span class='descriptor'>Comments:</span> 31 pages, v2: version to be published </div> <div class='list-subjects'><span class='descriptor'>Subjects:</span> <span class="primary-subject">High Energy Physics - Phenomenology (hep-ph)</span>; High Energy Physics - Theory (hep-th) </div> <p class='mathjax'> Feynman integrals are very often computed from their differential equations. It is not uncommon that the $\varepsilon$-factorised differential equation contains only dlog-forms with algebraic arguments, where the algebraic part is given by (multiple) square roots. It is well-known that if all square roots are simultaneously rationalisable, the Feynman integrals can be expressed in terms of multiple polylogarithms. This is a sufficient, but not a necessary criterium. In this paper we investigate weaker requirements. We discuss under which conditions we may use different rationalisations in different parts of the calculation. In particular we show that we may use different rationalisations if they correspond to different parameterisations of the same integration path. We present a non-trivial example -- the one-loop pentagon function with three adjacent massive external legs involving seven square roots -- where this technique can be used to express the result in terms of multiple polylogarithms. </p> </div> </dd> <dt> <a name='item58'>[58]</a> <a href ="/abs/2503.02055" title="Abstract" id="2503.02055"> arXiv:2503.02055 </a> (replaced) [<a href="/pdf/2503.02055" title="Download PDF" id="pdf-2503.02055" aria-labelledby="pdf-2503.02055">pdf</a>, <a href="https://arxiv.org/html/2503.02055v2" title="View HTML" id="html-2503.02055" aria-labelledby="html-2503.02055" rel="noopener noreferrer" target="_blank">html</a>, <a href="/format/2503.02055" title="Other formats" id="oth-2503.02055" aria-labelledby="oth-2503.02055">other</a>] </dt> <dd> <div class='meta'> <div class='list-title mathjax'><span class='descriptor'>Title:</span> Time operator from parametrization invariance and implications for cosmology </div> <div class='list-authors'><a href="https://arxiv.org/search/gr-qc?searchtype=author&query=Dimakis,+N">N.

We define the corresponding quantum operator, which results in being canonically conjugate to that of the vanishing Hamiltonian. In the context of particle dynamics, this leads to an uncertainty relation of the form $\Delta E_0 \,\Delta T \geq \hbar$, where $E_0$ is the rest energy of the particle. By studying the non-relativistic limit, we show that the action of the operator reduces to multiplication by the classical time coordinate. Finally, we derive the generic expression for the introduced time variable in the cosmological setting. </p> </div> </dd> <dt> <a name='item59'>[59]</a> <a href ="/abs/2503.23556" title="Abstract" id="2503.23556"> arXiv:2503.23556 </a> (replaced) [<a href="/pdf/2503.23556" title="Download PDF" id="pdf-2503.23556" aria-labelledby="pdf-2503.23556">pdf</a>, <a href="https://arxiv.org/html/2503.23556v2" title="View HTML" id="html-2503.23556" aria-labelledby="html-2503.23556" rel="noopener noreferrer" target="_blank">html</a>, <a href="/format/2503.23556" title="Other formats" id="oth-2503.23556" aria-labelledby="oth-2503.23556">other</a>] </dt> <dd> <div class='meta'> <div class='list-title mathjax'><span class='descriptor'>Title:</span> Neutrino Scattering: Connections Across Theory and Experiment </div> <div class='list-authors'><a href="https://arxiv.org/search/hep-ex?searchtype=author&query=Ashkenazi,+A">A.
