Hep-Th, or high-energy theoretical physics, explores the fundamental building blocks of our universe and the forces that govern them. Researchers in this field use complex mathematics to understand everything from subatomic particles to the behavior of black holes, often pushing the boundaries of what we know about space and time.
At Gist.Science, we monitor the arXiv repository to ensure you stay ahead of the curve in this rapidly evolving discipline. For every new preprint uploaded to arXiv under this category, our team generates both accessible plain-language overviews and detailed technical summaries, making cutting-edge research understandable regardless of your background.
Below are the latest papers in high-energy theoretical physics, curated to help you navigate the most significant recent discoveries.
This paper presents the Hamiltonian formulation of a gravity model derived from (A)dS Yang-Mills theory, demonstrating that in the Poincaré contraction limit with a specific gauge condition, the theory possesses only two propagating physical degrees of freedom.
This paper formulates a covariant, six-dimensional fracton electrodynamics using a symmetric tensor gauge field, demonstrating how gauge invariance naturally enforces charge immobility and dipole mobility while revealing a universal trace structure in the stress-energy tensor that becomes a total derivative in six dimensions.
This paper calculates the one-loop correction to the near-extremal quantum entropy of a charged 2D black hole using a worldsheet WZW model formulation, revealing that while the correction is typically exponentially suppressed at low temperatures, a specific fine-tuning of parameters yields a scaling that signals a worldsheet realization of the black hole/string transition.
This paper proposes a physical framework where primary and secondary invariants of gauge-invariant operator rings correspond to perturbative degrees of freedom and non-perturbative states, respectively, and demonstrates this algebraic structure using zero-dimensional matrix integrals.
This paper analyzes the double Wick rotation of a rotating BTZ black hole to derive a dual transition matrix with an imaginary chemical potential, demonstrating that geometric and time-like entanglement entropies can be reproduced through specific coordinate identifications and defining a new Lorentzian entanglement growth based on the linear growth coefficient of the time-like entropy.
This paper investigates stringy effects on holographic complexity in Gauss-Bonnet gravity using the "complete volume" proposal, revealing that while higher-curvature terms introduce a competition effect in static black holes, the complexity growth rate in dynamical spacetimes remains universally governed by conserved momentum and preserves the logarithmic dependence of scrambling time despite novel velocity jumps.
This paper develops a collective kernel effective field theory for pre-activation ResNets to derive exact stochastic recursions and continuous-depth ODEs for kernel statistics, ultimately revealing that a -only state-space reduction fails at finite depths due to accumulated transport errors and source closure mismatches, thereby necessitating the inclusion of the sigma-kernel for accurate modeling.
This paper employs the Dirac-Bergmann algorithm to demonstrate that introducing fixed external currents into Seiberg-Witten mapped non-commutative electrodynamics creates a source-compatibility obstruction located within the Dirac constraint chain, which typically resolves by fixing the primary multiplier rather than generating new constraints, thereby limiting a complete reduced-phase-space analysis to specific first-class subcases.
This paper presents a simple general relativity model coupled to a constrained scalar triplet and a non-propagating three-form sector that yields a continuous family of asymptotically flat, geometrically regular black holes with topological hedgehog scalar hair, a de Sitter core, and Schwarzschild-like asymptotic behavior corrected only at order .
This paper computes the efficiency of reversible Stirling engines across diverse working substances, identifying that regeneration can drive the efficiency toward the Carnot limit when the fixed-volume heat capacity is volume-independent, while demonstrating that for holographic CFTs dual to AdS black holes, the efficiency asymptotically approaches the Carnot value in the large-potential limit.
