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.

Tensionless hybrid strings in AdS3×S3×S3×S1\rm AdS_3\times S^3\times S^3\times S^1: Free field realisation

This paper presents a Wakimoto-like free field realization of the d(2,1;α)1\mathfrak{d}(2,1;\alpha)_1 current algebra at level k=1k=1 without gauging, demonstrating that the resulting tensionless hybrid string partition function precisely reproduces the single-particle spectrum of the symmetric orbifold theory SymN(S02)\text{Sym}^N(\mathcal{S}'_0{}^2).

Charged Black Holes in Bumblebee gravity with Global Monopole: Thermodynamics and Shadow

This paper investigates the thermodynamic properties, optical characteristics (including black hole shadows), particle trajectories, innermost stable circular orbits, and greybody factors of a charged black hole in bumblebee gravity with a global monopole, specifically analyzing how Lorentz symmetry violation and the monopole influence these physical phenomena.

The ZN×3\mathbb{Z}_N^{\times 3} symmetry protected boundary modes in two-dimensional Potts paramagnets

This paper constructs and analyzes one-dimensional boundary Hamiltonians derived from two-dimensional ZN×3\mathbb{Z}_N^{\times 3} symmetry-protected topological phases on a triangular lattice, revealing that their edge mode structures are governed by the arithmetic properties of NN—manifesting as commuting Temperley-Lieb algebras for prime NN and hierarchical factorized forms for composite NN—while demonstrating that all such phases arise from primary models augmented by local defects and exhibit anomalous projective symmetry realizations.

Superconformal index for N=4\mathcal{N} = 4 Super Yang-Mills and Elliptic Macdonald Polynomials

This paper establishes a connection between the superconformal index of N=4\mathcal{N}=4 U(N)U(N) Super Yang-Mills theory and the elliptic Ruijsenaars-Schneider integrable system by expressing the index in terms of elliptic Macdonald polynomials, which enables a systematic perturbative expansion in the elliptic parameter and recovers known results in specific limits.

Stability analysis and double critical phenomenon in the Einstein-Maxwell-scalar theory

This paper investigates the stability and phase transitions in a holographic superfluid model with higher-order self-interactions and non-minimal coupling, revealing that thermodynamic and dynamical stabilities are consistent and demonstrating a novel double critical phenomenon where increasing the non-minimal coupling parameter causes the system to transition from a first-order phase transition region to a supercritical region and then back to a first-order region.
