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 investigates the dynamics, ringdown, and accretion-driven quasi-periodic oscillations of Kerr-Bertotti-Robinson black holes, demonstrating how mass, rotation, and magnetic fields influence particle motion, scalar quasinormal modes, and the formation of distinct accretion structures that generate multiple QPOs.
This paper theoretically estimates the lowest boundary of the axion mass to be greater than 5.885 microelectron-Volts by analyzing the energy spectrum of electrons in magnetic fields and applying these results to hyperfine transitions in hydrogen atoms and solar axion emission.
This paper demonstrates that the two-dimensional Ising model on de Sitter spacetime serves as an exactly solvable laboratory for studying quantum field theory dynamics, revealing how non-perturbative exact calculations of cosmological correlators resolve the late-time divergences that plague standard conformal perturbation theory.
This paper demonstrates that imposing tree-level factorization, a specific "peculiar parity" condition, and positivity on four-dimensional supergravity effective field theories restricts the allowed Wilson coefficients to a non-convex domain containing only the closed superstring Virasoro–Shapiro amplitude and an infinite spin tower, with the former being the unique solution if a finite number of states is required near the first mass level.
This paper demonstrates that controlled violations of the null energy condition in a holographic model dual to a non-Hermitian -symmetric QFT lead to a novel black hole interior characterized by an isotropic Little Rip cosmology, which can be distinguished from standard Kasner regimes via heavy-operator correlators.
This paper confirms the existence of a MOND-type gravitational anomaly in wide binary stars at low accelerations by demonstrating that rigorous data quality control and realistic modeling of multiple-star systems cannot eliminate the observed deviation from standard gravity, attributing conflicting previous results to calibration biases, unaccounted selection effects, or insufficient statistics.
This paper presents a nonperturbative analytic framework for multifield inflation that resums strong curvature-isocurvature mixing to all orders, deriving exact bispectrum expressions that reveal dramatic enhancements and distinctive scaling laws in the strong-mixing regime where conventional perturbation theory fails.
This paper systematically investigates beyond-cohomology bosonic SPT and invertible phases, identifying a mod-3 non-triviality and demonstrating that their classification on general simplicial complexes is dual to Steenrod's problem regarding homology cycles without manifold representatives, thereby explaining how certain Dijkgraaf-Witten phases become trivial when restricted to manifolds.
This paper investigates cosmological collider signatures in a two-field inflationary system with constant-turn derivative mixing by utilizing exact hypergeometric solutions and a Mellin-Barnes approach to derive the full non-perturbative dependence of the squeezed bispectrum's oscillation amplitude and phase on the mixing strength and heavy field mass.
This paper introduces a class of regular axisymmetric black hole geometries characterized solely by mass and spin that interpolate between regular spacetimes and the Kerr solution, featuring quasi-extremal configurations independent of the spin-mass ratio and offering a framework for analytically describing Kerr black hole formation.
