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.

The spectral gap of the ABJM model: A holographic perspective from uplifted higher-dimensional geometries

This paper investigates the spectral gap and fermionic response of the ABJM model by analyzing a U(1)4U(1)^4 charged black brane in four-dimensional gauged supergravity and its uplifts to five and eleven dimensions, demonstrating that the gap arises from unequal chemical potentials and that the near-horizon geometry exhibits decoupling sectors resembling BTZ×S2\mathrm{BTZ} \times \mathrm{S}^2 or AdS3×R2\mathrm{AdS}^3 \times \mathbb{R}^2.

Anomaly quenching and dynamical cooling of Hawking evaporation in Horndeski gravity

This paper demonstrates that first-order Horndeski scalar-tensor couplings induce a dynamical cooling effect in two-dimensional CGHS black holes, causing Hawking evaporation to halt and potentially form stable macroscopic remnants that preserve quantum information and modify the Page curve without violating horizon regularity.

The two-sided Bogoliubov inequality in von Neumann algebras conceptualizes the free energy--quantum correlations link

This paper generalizes the two-sided Bogoliubov inequality to arbitrary von Neumann algebras using Araki-Uhlmann relative entropy and unbounded KMS perturbation theory, thereby establishing a thermodynamic criterion for quantifying entanglement in infinite-dimensional quantum systems.

Spectral Topology and Universal Krylov Dynamics

This paper establishes that the global topology of spectral measures, rather than just their asymptotic tails, encodes a finer hierarchy of universal Krylov dynamics invariants, revealing how spectral gaps, band structures, and gap-closing transitions govern the sub-leading corrections and oscillatory behavior of Lanczos coefficients through connections to orthogonal polynomials and Painlevé transcendents.

Chiral Doubling of Heavy-Light Hadrons and the New Beauty--Strange Bs0(5700)0B_{s0}^*(5700)^0 Candidate

This paper interprets the LHCb observation of the Bs0(5700)0B_{s0}^*(5700)^0 meson as the chiral partner of the ground state Bs0B_s^0, thereby validating the chiral doubling scenario for heavy-light hadrons and predicting the existence of a yet-unobserved narrow 1+1^+ beauty-strange meson at approximately 5747 MeV.

Conformal Killing Gravity: New Constraints from DESI DR2 BAO datasets

This paper investigates Conformal Killing Gravity, a geometric framework where dark energy emerges from conformal Killing symmetry without empirical parametrization, and finds that constraints from recent cosmological datasets (including DESI DR2 and Planck PR4) favor a quintessence-like evolution approaching a cosmological constant while predicting a future expansion turning point, though the model fails to fully resolve the H0H_0 tension.

Analytic Spread Complexity from Level Statistics: From Chaos to Integrability

This paper establishes an analytic framework linking spread complexity to local spectral statistics by demonstrating that the Krylov kernel's banded structure allows the complexity's finite-time peak and late-time behavior to be directly expressed through the Fourier transforms of nearest-neighbour spacing distributions, thereby unifying the description of both chaotic and integrable quantum systems.

Constraints on magnetic monopoles from X-ray observations of neutron stars

This paper utilizes archival X-ray observations of old isolated neutron stars to establish the most stringent constraints to date on the Galactic magnetic monopole flux for masses between 101110^{11} and 101310^{13} GeV/c², demonstrating that such observations provide a powerful probe for detecting monopole-induced heating via nucleon decay catalysis.
