hep-th papers | Gist.Science

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.

Particle Dynamics, Shadow and Hawking Sparsity of a Kalb-Ramond Black Hole Coupled to Nonlinear Electrodynamics

This paper investigates the geodesic structure, black hole shadow, and Hawking sparsity of a static, spherically symmetric black hole sourced by a Kalb-Ramond field coupled to nonlinear electrodynamics, demonstrating that the combined effects of the field and magnetic charge significantly increase the sparsity of the Hawking cascade while maintaining consistency with Event Horizon Telescope observations of M87* and Sgr A*.

When Symmetries Twist: Anomaly Inflow on Monodromy Defects

This paper investigates monodromy defects in gapped SPT and gapless anomalous theories, demonstrating that background magnetic flux sources anomalies to dress these defects with topological order, thereby inducing protected chiral edge modes and the adiabatic pumping of gapless degrees of freedom.

Bouncing singularities in Schwarzschild: a geometric origin of the QNM convergence region

This paper analytically demonstrates that the convergence region of the Schwarzschild quasinormal mode expansion is determined by a geometric "bouncing singularity" in the complex time plane, caused by a null geodesic reflecting off the black hole singularity, which explains the observed bounds on real-time convergence and the annular convergence of Matsubara mode sums.

5d Trinions and Tetraons

This paper utilizes M-theory geometric engineering to construct and classify 5d SCFTs known as trinions and tetraons with D-type flavor symmetry, which form non-linear generalized quivers with novel instantonic symmetry enhancement, while simultaneously demonstrating that such structures cannot exist for E-type symmetries.

Quantum-statistical constraints on Kerr-anti-de Sitter thermodynamics

This paper establishes a general framework for Kerr-anti-de Sitter black hole thermodynamics that reconciles geometric and quantum-statistical considerations, demonstrating that observer-dependent kinematic quantities and gauge-fixed dynamical terms restrict the infinite family of thermodynamic descriptions to a unique, physically consistent subclass.

Evaporating Black Hole Interior and Complexity Evolution

This paper demonstrates that in an evaporating Jackiw-Teitelboim black hole model, the subsystem complexity—probed via geodesic length—grows linearly to a peak at the Page time before decaying exponentially, a behavior driven by non-perturbative gravitational effects that cause a loss of self-averaging at late times.

Shifted quantum toroidal algebra of type $\mathfrak{gl}_{1|1}$ and the Pieri rule of the super Macdonald polynomials

This paper establishes that the action of super charges in the shifted quantum toroidal algebra of type $\mathfrak{gl}_{1|1}$ on the level zero super Fock module yields a Pieri rule for super Macdonald polynomials, which is expressed via differential operators to derive supersymmetric Hamiltonians that recover previously known results.

Static electromagnetic Love tensors of 5-dimensional Myers-Perry black holes

This paper investigates static electromagnetic and gravitational perturbations of five-dimensional Myers-Perry black holes, demonstrating that while the electric polarization reduces to a massless scalar field, the magnetic and gravitational sectors yield special Heun equations with exact hypergeometric solutions that reveal a non-trivial mixing of angular momentum modes in the static tidal Love tensors.

Covariant extrinsic curvature expansion of the nonlocal effective action for a massless scalar field on a manifold with boundary

This paper employs a heat-kernel approach to derive a covariant expansion of the nonlocal effective action for a massless scalar field on a flat manifold with a curved boundary, extending previous results to general surfaces and applying the framework to calculate particle-creation rates for oscillating deformed geometries in 2+1 and 3+1 dimensions.

Joule-Thomson effect and Efficiency of deformed AdS-Schwarzschild black hole in presence of quintessence

This paper investigates the Joule-Thomson expansion and thermodynamic efficiency of a deformed AdS-Schwarzschild black hole in the presence of quintessence, demonstrating how the deformation parameters $\alpha$ , $\beta$ , and $\sigma$ collectively govern the system's heating-cooling behavior, thermal stability, and heat engine efficiency.
