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 proposes a framework where spatial subregions in quantum gravity are assigned pure states via a partially frozen gravitational path integral, leading to a new holographic prescription for entanglement entropy that satisfies key consistency conditions and introduces an observer-dependent entanglement wedge.
By combining Bayesian inference with hydrodynamic simulations and Large Hadron Collider data from Xe-Xe and Pb-Pb collisions, researchers successfully reconstructed the nearly maximally triaxial ground-state shape of the Xe nucleus, thereby establishing high-energy collider experiments as a quantitative tool for probing proton-neutron correlations driven by quantum chromodynamics.
This paper establishes a universal "Weyl double copy" relation for all four-dimensional type D vacuum spacetimes, linking their gravitational curvature to electromagnetic field strengths and resolving ambiguities in previous Kerr-Schild formulations while providing new double-copy interpretations for the C-metric and Eguchi-Hanson instanton.
This paper investigates celestial chiral algebras in self-dual Yang-Mills and gravity theories, demonstrating how deformations of the algebra and the resulting operator-product expansions manifest colour-kinematics duality to ensure classical integrability and the vanishing of tree-level scattering amplitudes via the double copy.
This paper argues that non-local inter-particle interactions are essential for the stability of dark matter halos, demonstrating that standard collision-less models fail without such effects and revealing distinct stability behaviors and boundary characteristics between fermionic and bosonic dark matter candidates.
This paper proposes that the strongly coupled phase diagram of QED with two Dirac fermions, including its time reversal symmetry, SPT phases, and anomalies, can be fully reproduced by gluing together two standard Wilson-Fisher theories through a mechanism termed "SPT absorption."
This paper provides numerical evidence supporting the non-Abelian eigenstate thermalization hypothesis (ETH) through simulations of a 1D Heisenberg chain and offers an analytical proof of its self-consistency, thereby establishing a framework for understanding thermalization in quantum systems with non-commuting conserved quantities.
This paper calculates the one-loop radiative correction to the Casimir energy for massive and massless Lorentz-violating scalar fields confined between rough membranes in 3+1 dimensions under various boundary conditions, utilizing position-dependent counterterms and the Box Subtraction Scheme to handle divergences.
This paper establishes a first-principles framework based on non-local Kadanoff-Baym equations that unifies macroscopic fluid dynamics and microscopic particle interactions to systematically determine bubble wall velocity, revealing a linear friction force from scattering that prevents runaway bubbles in the ballistic regime.
This paper proposes replacing the singularity in maximally extended Schwarzschild Anti-de Sitter spacetimes with a non-metastable de Sitter infinitesimal patch, suggesting this modification could regulate late-time correlators, influence holographic complexity growth, and contribute to resolving the black hole information paradox via the Page Curve.
