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 constructs a non-Abelian T-dual pair for the background using Poisson-Lie T-duality, demonstrating that the dual geometry satisfies one-loop beta-function equations, preserves the original solution at large distances, and yields seven distinct D-brane configurations linked by a symmetric duality action.
This paper investigates Krylov spread complexity for time-dependent quantum systems by formulating the problem within Floquet theory for periodic driving and extending the framework to general time-dependent cases using both globally and piecewise truncated Magnus expansions to ensure reliable analysis when standard expansions fail.
This paper develops a microscopic quantum membrane paradigm for black holes by modeling the horizon as a fuzzy sphere populated by half-filled Fermi sea partons, demonstrating how their coupling to a Berry monopole generates Lowest-Landau-Level currents that dynamically lock to external fields, thereby replacing the classical fictitious membrane with a dynamical quantum structure that yields frequency- and helicity-dependent corrections to horizon boundary conditions.
This paper investigates how non-minimal coupling between photons and the Weyl tensor induces vacuum birefringence around a black hole, leading to polarization-dependent phenomena such as split photon spheres, double shadows, and a unique backward birefringence signal that serves as a clean diagnostic for the coupling strength.
This paper presents a new family of regular black holes with Minkowskian cores constructed via gravitational decoupling and demonstrates that, despite their distinct non-singular interiors, their optical signatures such as shadows and accretion disk images are nearly indistinguishable from those of standard singular Schwarzschild and Kerr black holes.
This paper establishes a novel analytical framework linking Krylov complexity to the Loschmidt amplitude by expressing the former as a derivative with respect to an angular perturbation, thereby deriving general relations between survival amplitudes and complexity measures while proposing a classification scheme for quantum dynamics based on perturbation strength.
This paper argues that the conclusion that wormholes explicitly break global symmetries is premature, demonstrating that the ensemble average over symmetry-breaking parameters is typically dominated by the symmetric point due to doubly exponential suppression of other configurations, thereby resolving the conventional axion quality problem in standard Peccei–Quinn models.
This paper reformulates classical satellite and splice constructions in knot theory as multilinear TQFT operators acting on torus Hilbert spaces, demonstrating how the JSJ decomposition of link complements organizes these states into networks of elementary operators that yield distinct entanglement entropy patterns.
This paper demonstrates that introducing an additional derivative interaction in non-minimally coupled Proca theories can eliminate the zero-speed strong-coupling problem by restoring non-degenerate scalar dynamics, thereby identifying a stable de Sitter fixed point with a non-vanishing temporal vector condensate where no-ghost and stability conditions are satisfied.
This paper derives the Belinfante–Rosenfeld symmetrization procedure from metric-affine conservation laws by showing that the divergence of the hypermomentum current, defined via minimal coupling to an independent affine connection, reproduces the Belinfante improvement term in the flat-spacetime limit, a result explicitly demonstrated for Quantum Electrodynamics and Quantum Chromodynamics.
