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.

Generalized Symmetries From Fusion Actions

This paper establishes a Galois correspondence between specific fusion subcategories of AA-modules and condensable subalgebras of a condensable algebra AA in a modular tensor category via a generalized fusion action, while also proving a categorical Schur-Weyl duality and demonstrating that this framework recovers known results for vertex operator algebras and finite group actions.

Surface Topological Quantum Criticality II: Conformal manifolds, Isolated fixed points and Entanglement

This paper proposes a framework for realizing conformal manifolds in two-dimensional quantum systems, demonstrating how quantum fluctuations in the large-NcN_c limit drive renormalization-group flows toward isolated Wilson-Fisher fixed points while linking the flow direction to increased entanglement entropy and emergent dynamical symmetries.

An improved formula for Wigner function and spin polarization in a decoupling relativistic fluid at local thermodynamic equilibrium

This paper presents an improved formula for the Wigner function and spin polarization of fermions in a decoupling relativistic fluid by introducing a new expansion method that captures geometric dependencies in the spin-shear term, naturally justifies the isothermal condition, and extends the framework to particles with arbitrary spin.

4d Maxwell on the Edge: Global Aspects of Boundary Conditions and Duality

This paper investigates the global aspects of boundary conditions and dualities in 4d Maxwell theory with a boundary, demonstrating how topological interfaces generate an SL(2,Q)SL(2,\mathbb{Q}) action on the bulk coupling and providing a unified SymTFT framework to characterize the resulting boundary symmetries and edge modes.

Gravitational equal-area law and critical phenomena of cuspy black hole shadow

This paper establishes a gravitational equal-area law to analyze the topological transition of black hole shadows from a charge of 1 to -1 during cusp formation, revealing a critical point with a 1/2 exponent that places the system within the mean-field universality class and offers a new framework for testing fundamental physics beyond the Kerr paradigm.

Multi-particle correlators with higher KK modes I: a bootstrap approach

This paper employs a bootstrap approach to uniquely determine tree-level supergravity four-point correlators on AdS5×_5\timesS5^5 involving one double-particle and three single-particle operators using only large-NN and large 't Hooft coupling consistency, thereby verifying these results against a conjectured five-point correlator limit and providing further evidence for the latter.
