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.

Observation of Robust and Coherent Non-Abelian Hadron Dynamics on Noisy Quantum Processors

This study demonstrates the first observation of robust, coherent non-Abelian hadron dynamics on a noisy 156-qubit quantum processor by simulating a 60-site SU(2) lattice gauge theory using a hardware-efficient encoding, successfully capturing meson propagation and breathing modes while outperforming classical approximation methods in the weak-coupling regime.

On Type II0_0 Loci in Moduli Space

This paper demonstrates that type II0_0 loci in the moduli space of type IIB string theory compactified on Calabi-Yau manifolds arise from integrating out a non-perturbative sector of light electric and magnetic states, which admits an effective weakly-coupled infrared description via a complex-charged BPS state and implies the existence of infrared emergent infinite distance loci in quantum gravity.

Batalin-Fradkin-Vilkovisky quantization of Einstein gravity with off-diagonal solutions encoding Hořava type generating functions

This paper develops and applies the Batalin-Fradkin-Vilkovisky (BFV) formalism to quantize off-diagonal solutions of Einstein's equations on Lorentz manifolds with nonholonomic fibrations, demonstrating that these solutions encode Hořava-Lifshitz configurations with anisotropic scaling and effective cosmological constants in the quasi-classical limit.

Complexity and Operator Growth in Holographic 6d SCFTs

This paper investigates Krylov complexity in holographic six-dimensional N=(1,0){\cal N}=(1,0) superconformal field theories by analyzing massive geodesic probes in massive type IIA supergravity, demonstrating that while internal symmetries and quiver structures influence early-time dynamics, the late-time growth of the generalized proper momentum remains linear, consistent with operator growth in conformal theories.

Thermal enhancement of inflationary magnetic fields

This paper proposes that assuming a thermal initial state for gauge fields during inflation, rather than the standard vacuum, introduces a dissipative boost that enhances primordial magnetic fields by up to 101610^{16}, suggesting that embedding this mechanism in a warm inflation framework offers a promising path to inflationary magnetogenesis without requiring non-minimal couplings or modified electrodynamics.

Towards Two-to-Two Scattering of Scalars in Asymptotically Safe Quantum Gravity

This paper computes the graviton-mediated two-to-two scattering amplitude and cross-section for scalar particles within asymptotically safe quantum gravity by determining the full momentum dependence of the scalar-graviton vertex via the functional renormalization group, demonstrating that the results recover General Relativity at low energies while preserving unitarity in the ultraviolet regime.

States of 2D Yang-Mills and Large-Volume Entanglement

This paper investigates entanglement in two-dimensional Yang-Mills theory, revealing that while standard Euclidean path integral states become separable at infinite volume, specific configurations involving Wilson lines and loops maintain finite entanglement through projectors onto non-trivial vacuum sectors, offering new insights into large-volume confinement transitions.
