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.

Rotation and Anisotropic Scaling in Axionic Holographic Superconductors: AdS4_4 versus Lifshitz5_5

This paper investigates how rotation and anisotropic scaling jointly influence the onset of condensation in holographic superconductors by comparing rotating axionic black holes in AdS4_4 and Lifshitz5_5 backgrounds, revealing that rotation suppresses the condensate while increasing the dynamical exponent enhances it within complete correlated families of solutions.

Coherent Release Fronts in Krylov Chains and Thermal AdS2_2 Response

This paper derives an exact occupation kernel describing coherent release from finite Krylov sectors into conformal tails with linear Lanczos coefficients, revealing how emission profiles encode serial step counts and resonance interference, and applies these findings to a thermal AdS2_2 realization where a shallow sector coupled to a conformal tail reproduces the leading complex pole.

On-shell renormalization of sine-Gordon by the quantum inverse scattering method

This paper proposes an on-shell renormalization scheme for the sine-Gordon model within the quantum inverse scattering method, where the entire cutoff dependence is absorbed into a length rescaling factor ZLZ_L without renormalizing the field or coupling, thereby directly yielding exact soliton and breather mass ratios that interpolate between classical and semiclassical limits while highlighting the interplay between integrability and renormalization.

The Scalar MSW Effect: Compact analytical formulas for neutrino oscillations with large matter effects, including μ−μ\mu -\mu and τ−τ\tau -\tau dominant matter potentials

This paper extends the Jacobi diagonalization method to derive compact, accurate analytical formulas for three-flavor neutrino oscillations in matter, revealing that scalar non-standard interactions can induce an energy-independent resonant "scalar MSW" effect and providing effective parameter mappings for both standard and exotic matter potentials.

Vacuum entanglement in a time-dependent electric field

This paper investigates how a time-dependent homogeneous electric field influences vacuum entanglement in a charged scalar field, revealing that while the field enhances total correlations and state mixedness via the Schwinger effect, it causes distillable entanglement between disjoint regions to decrease and eventually vanish, with correlation distributions acquiring a nontrivial directional dependence due to background anisotropy.

Complexity study of the Hartle-Hawking state in JT gravity

This paper investigates the growth of quantum complexity for the Hartle-Hawking state in Jackiw-Teitelboim gravity using the Wigner function negativity in the length basis, revealing that the state remains a minimum-uncertainty Gaussian with positive Wigner function at early times before saturating at late times, thereby demonstrating that the length basis provides an ideal semi-classical framework for describing chaotic quantum dynamics without exhibiting the spectral ramp seen in other measures.
