hep-th papers | Gist.Science

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.

Plummer Dark Matter Black Hole with Topological Defects: Shadow, Greybody Factors, Quasinormal Modes, and Thermodynamics

This paper presents a static, spherically symmetric black hole solution embedded in a Plummer dark matter halo and a Letelier cloud of strings, systematically analyzing its geometric properties, shadow, deflection angle, scalar perturbations, and thermodynamics to demonstrate that the string-cloud tension parameter $\alpha$ drives leading-order modifications to all observables while the dark matter halo density $\rho_0$ provides only subdominant corrections.

Symplectic structure in open string field theory III: Electric field

This paper utilizes a new symplectic structure formula in open string field theory to demonstrate that the energy of a D-brane with constant electric flux, calculated via a generalized Ellwood invariant, is consistent with the result derived from the Dirac-Born-Infeld action.

Descending into the Modular Bootstrap

This paper employs machine-learning-style optimization, featuring a novel singular-value-based optimizer and uncertainty estimation, to numerically explore the landscape of two-dimensional conformal field theories with central charges between 1 and 8/7, identifying candidate spectra in a previously uncharted region and suggesting a tighter constraint on the spectral gap near $c=1$ .

Sven: Singular Value Descent as a Computationally Efficient Natural Gradient Method

The paper introduces Sven, a computationally efficient natural gradient optimization algorithm that utilizes a truncated singular value decomposition of the loss Jacobian to simultaneously satisfy individual data point residuals, offering faster convergence and lower final loss than standard first-order methods on regression tasks while scaling linearly with the number of retained singular directions rather than quadratically with the number of parameters.

Is Gravity Always Enough to Yield a Classical Universe?

This paper challenges the conventional view that gravity and inflation always ensure a classical universe by demonstrating that non-linear dynamics beyond slow roll can preserve non-classical features in cosmic structure, proposing Wigner function-based phase-space analysis as a method to detect these potential quantum signatures.

Quantum structure of the chiral vortical effect and boundary-induced vortical pumping

This paper presents an exact quantum solution for rotating Weyl fermions in a finite cylinder, revealing that the bulk chiral vortical effect is a magnetization current while uncovering a new, temperature-independent boundary-induced vortical pumping mechanism that transports axial charge via chiral modes dependent on the number of Weyl nodes.

Bootstrapping Symmetries in Quantum Many-Body Systems from the Cross Spectral Form Factor

This paper introduces a bootstrap framework that utilizes the cross spectral form factor and spectral correlations to systematically reconstruct the full representation theory and identify hidden finite group symmetries in quantum many-body systems, including their character tables and fusion rules, without prior knowledge of the symmetry group.

AI usage in string theory, a case study: String Vacua in the Interior of Moduli Space

This paper presents an AI-assisted review of recent computational advances in stabilizing four-dimensional $\mathcal{N}=1$ Minkowski vacua within the interior of moduli space for specific type IIB string compactifications, highlighting how higher-order flux superpotential terms and exact worldsheet descriptions provide critical data for testing string landscape and swampland conjectures.

Phase-space integrals through Mellin-Barnes representation

This paper presents an analytical computation of angular phase-space integrals with three and four denominators using dimensional regularisation and the Mellin-Barnes representation, expressing the results in terms of Goncharov polylogarithms and deriving recursion relations to facilitate the solution of full phase-space integrals.

The scaling Pomeron

This paper derives a positive-signature Pomeron amplitude with specific scaling properties that successfully describes the dip-bump region of $pp$ elastic scattering differential cross-sections at LHC energies through an analytic continuation of $t$ -channel partial waves featuring poles at fractional values on the real axis.
