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 semiclassical evolution of Hawking atmospheres around evaporating anti-de Sitter black holes by combining the Parikh-Wilczek tunneling method with renormalized energy-momentum tensor calculations to reveal significant deviations from ideal blackbody behavior driven by strong backreaction effects.
This paper proposes a novel method to probe the validity limits of the semiclassical Einstein equation by constructing a controlled, analytically tractable scenario where a mixture of weak-gravity quantum states drives the system into a strong-gravity regime, allowing for a direct comparison between quantum and semiclassical predictions via a branch-degenerate observable.
This paper investigates a generalized WKB ansatz for the quantum propagator by introducing an additive exponent as a measure of quantumness, analyzing its role through the Hamilton-Jacobi equation, and exploring its application to various systems, field theories, and Hamiltonian-constrained dynamics.
This paper demonstrates that the rate at which chiral fermion localisation is lost during domain wall merging in extra-dimensional braneworlds follows a universal power law determined solely by the Jackiw-Rebbi topological index, rendering the collapse of four-dimensional Yukawa couplings insensitive to the specific microscopic scalar dynamics of the walls.
This paper investigates the thermodynamic properties, Hawking-radiation sparsity, and greybody factors of a hairy Kiselev black hole surrounded by quintessential matter, revealing how exponential hair and quintessential fields respectively govern small-scale and large-scale behaviors, induce phase transitions, and cause highly intermittent radiation emission.
This paper explores universalities in the partition functions of various low-dimensional quantum gravity models by analyzing their holographic connections, parameter dependencies, spectral properties, and entanglement-related phenomena such as wormholes and defects.
This paper advances the loop expansion of the quantum Magnusian by developing an efficient diagrammatic algorithm that utilizes color and black-and-white bases to derive Murua coefficients, ultimately establishing edge contraction rules that enable the direct recursive computation of matrix elements through graph manipulations alone.
This paper employs a dynamical systems framework with a phenomenological relaxation time parameter to model black hole thermodynamic criticality, revealing universal relaxation scaling laws and critical slowing down that classify black holes into distinct universality classes based on their local bifurcation structures.
This paper investigates the renormalized fermion-gluon vertex, effective mass, and condensate for fermions propagating in an external non-Abelian plane-wave Yang-Mills field by utilizing an exact Green's function in the axial gauge, with applications discussed for strong-field QCD and non-Abelian Schwinger physics.
This paper investigates the form-factor dependence of Reggeized spin-2 Pomeron and spin-3 Odderon exchanges in high-energy elastic $pp$ and scattering, demonstrating that an exponential Odderon-proton form factor provides a superior fit to global data compared to other parametrizations and reveals a peripheral soft Odderon interaction with hadronic-scale transverse structure.
