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.

Equilibrium Partition Function of Non-Relativistic CFTs in Harmonic Trap

This paper investigates the equilibrium partition function of non-relativistic conformal field theories in harmonic traps, revealing that the logarithm of the partition function exhibits universal simple poles in the difference between the squared trapping frequency and squared angular velocities, with residues determined by the equation of state in the hydrodynamic regime and by specific thermodynamic variables in the large-angular-momentum limit.

Strong deflection of massive particles via the geodesic deviation equation

This paper develops a covariant formulation of the strong deflection limit for massive particles in static, spherically symmetric spacetimes, demonstrating that the logarithmic divergence of the deflection angle is governed by the radial instability exponent of the critical orbit, which can be expressed geometrically through local curvature data and matter properties.

On the structure of categorical duality operators

This paper systematically characterizes categorical duality operators on spin and anyon chains with internal fusion category symmetry by parameterizing them via quantum cellular automata and associated bimodule categories, demonstrating that such operators form a simplex whose extreme points correspond to simple objects, and proving that these structures inevitably flow to weakly integral fusion categories in the infrared limit when defined on tensor product Hilbert spaces.

Does hot QCD have a conformal manifold in the chiral limit?

Based on recent lattice evidence and 't Hooft anomaly constraints, this paper proposes that the chiral phase transition in hot QCD for Nf≥2N_f \ge 2 massless flavors may be described by a conformal manifold of θB\theta_B-dependent universality classes featuring an exactly marginal operator related to baryon density, rather than a standard Ginzburg-Landau critical point.

Shear Viscosity and Electrical Conductivity of Rotating Nuclear Medium in Hadron Resonance Gas and Nambu-Jona Lasinio Models

This paper investigates how rotation influences the anisotropic shear viscosity and electrical conductivity of strongly interacting matter by employing kinetic theory within Hadron Resonance Gas and Nambu-Jona-Lasinio models, revealing that rotation suppresses chiral condensates, generates a sizable Hall-like conductivity, and reduces transport coefficients relative to isotropic cases.

Gravitational four-derivative corrections in non-relativistic heterotic supergravity and the $SO(8)$ Green-Schwarz mechanism

This paper presents the first explicit construction of four-derivative gravitational corrections in non-relativistic heterotic supergravity by extending the Bergshoeff-de Roo identification, revealing a gravitational $SO(8)$ Green-Schwarz mechanism that establishes a systematic framework for incorporating higher-curvature dynamics into these backgrounds.

M2-brane partition functions and HD supergravity from equivariant volumes

This paper establishes a holographic correspondence between M2-brane partition functions and equivariant volumes of toric Calabi-Yau manifolds, rigorously testing the conjecture by deriving a universal Airy function representation for squashed S3S^3 partition functions that incorporates finite NN corrections and higher-derivative supergravity effects, while demonstrating agreement with localization results across various models including ABJM theory and its generalizations.
