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.

Thermal and Optical Signatures of Einstein-Dyonic ModMax Black Holes with GUP and Plasma Modifications

This paper investigates the thermodynamic and optical properties of Einstein-Dyonic-ModMax black holes by incorporating Generalized Uncertainty Principle corrections and plasma effects, revealing that non-linear electrodynamics and quantum gravity modifications lead to stable remnants, frequency-dependent lensing signatures, and rich phase transition structures.

Precision tests of bulk entanglement: AdS3AdS_3 vectors

This paper demonstrates that the holographic entanglement entropy of massive Chern-Simons fields in AdS3AdS_3, calculated via the Faulkner-Lewkowycz-Maldacena formula with vanishing edge mode contributions, precisely matches the single-interval entanglement entropy of the dual primary operator and its descendants in large-charge CFTs, thereby resolving a discrepancy with earlier massless limit calculations.

Probing chiral topological states with permutation defects

This paper introduces a novel method using permutation defects between ground-state replicas to extract chiral topological properties, such as the chiral central charge and Hall conductance, directly from bulk wavefunctions, thereby bridging the gap between bulk entanglement measures and boundary anomalies for both numerical and quantum device applications.

Chern-Simons couplings, modular duality, and anomaly cancellation in abelian F-theory

This paper demonstrates that the quantized Chern-Simons couplings in three-dimensional F-theory compactifications provide a scheme-independent, one-loop exact encoding of all four-dimensional abelian anomalies and their Green-Schwarz cancellation, a result derived by matching flux-induced M-theory terms with explicit one-loop integrations and confirmed through compatibility with type IIB modular duality.

Smoking Gun Signatures of Quasilocal Probability in Black Hole Ringdowns

This paper proposes that the concept of Quasilocal Probability in curved spacetime induces horizon-driven non-Hermitian dynamics in black hole ringdowns, producing a unique, correlated set of observational signatures that can be distinguished from generic modified gravity effects and tested with upcoming gravitational wave data to probe the fundamental nature of quantum mechanical Hermiticity.
