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 introduces a systematic bootstrap method that leverages the positivity of density matrices and steady-state conditions to analyze open quantum many-body systems on infinite lattices, successfully deriving bounds on critical parameters and spectral gaps for the quantum contact process exhibiting absorbing phase transitions.
This paper rederives and generalizes the connection between asymptotic symmetries and the memory effect in massive QED and perturbative quantum gravity by utilizing detector formalism and full time-dependent Faddeev-Kulish dressings to correct literature discrepancies and demonstrate that these dressings correctly encode memory effects, including contributions from external hard gravitons.
This paper introduces a novel class of conformal field theory defects called crosscap defects, which arise from quotienting spacetime by a automorphism to generalize CFT on real projective space, derives their associated crossing equations and conformal blocks, and analyzes their properties in the model, revealing the absence of displacement and tilt operators for generic dimensions.
This paper investigates a dark matter model consisting of millicharged magnetic monopoles from a dark U(1) sector with kinetic mixing to the Standard Model, deriving constraints on its parameters from dark matter self-interactions and the survival of galactic magnetic fields via the Parker effect across three distinct phenomenological scenarios.
This paper utilizes the Multiscale Entanglement Renormalization Ansatz (MERA) to investigate the critical line of the chiral clock model, revealing smoothly varying effective scaling exponents that support a slow renormalization group flow between the 3-state Potts fixed point and an anisotropic fixed point.
This paper determines the type-A and type-B Weyl anomaly coefficients for holographic co-dimension two defect CFTs at both weak and strong coupling, revealing a novel region where the type-A coefficient is negative and demonstrating agreement between the two coupling regimes in a specific limit.
This paper establishes a correspondence between the generalized Schur indices of 4d and superconformal field theories and the eigenfunctions of non-relativistic integrable models, such as the elliptic Ruijsenaars-Schneider and Inozemtsev systems, thereby deriving new mathematical identities and extending these relationships to various classes of SCFTs.
This paper demonstrates that the trapped interiors of black holes provide an exact, time-dependent framework for the classical double copy, proving that regular solutions like the Bardeen black hole yield finite single-copy gauge fields that satisfy standard energy conditions even when the corresponding gravitational core violates them.
This paper presents new regular black hole solutions in general relativity supported by nonlinear electrodynamics with de Sitter cores, reconstructing their Lagrangian, analyzing their physical properties and energy conditions, constraining parameters via Event Horizon Telescope observations of Sgr A*, and verifying their dynamical stability through quasinormal mode analysis.
This paper extends the framework of functional geometry to achieve off-shell covariance for correlation functions in massless scalar field theories by prioritizing observable invariance under field redefinitions, while demonstrating that this specific construction does not straightforwardly generalize to massive theories.
