Hep-Lat, short for High Energy Physics – Lattice, explores the fundamental forces of nature by simulating particle interactions on a digital grid. Instead of relying solely on abstract equations, researchers in this field use powerful computers to model how quarks and gluons bind together, offering deep insights into the structure of matter that are often impossible to derive analytically.
Gist.Science ensures these complex discoveries from arXiv remain accessible to everyone. We process every new preprint in this category as it is posted, providing both plain-language explanations for the curious and detailed technical summaries for experts. This dual approach bridges the gap between cutting-edge simulation work and broader scientific understanding.

Addressing the breakdown of Bloch's theorem in spatially varying composites, this paper establishes a foundational ab initio quantum theoretical framework for functionally graded materials that derives effective field equations for modulated Bloch states, revealing non-tensorial electromagnetic properties and enabling the predictive design of optimized electronic devices such as graded p-n junctions.
This paper computes the hadronic vacuum polarization to three loops in two-flavor chiral perturbation theory, identifying six elliptic master integrals and establishing previously unknown relations essential for renormalizability to provide a foundation for phenomenological and lattice QCD applications.
This paper presents a finite-temperature lattice study of Sp(4) Yang-Mills theory using the Logarithmic Linear Relaxation algorithm to characterize its first-order confinement/deconfinement phase transition, estimate discretization and finite-volume artifacts, and establish bounds for the continuum theory's critical coupling, specific heat, and surface tension.
The RC* collaboration utilizes their openQxD code to present preliminary baryon mass results, including the first computation of additional partially connected contributions for the baryon, from QCD+QED simulations employing C-periodic boundary conditions at an unphysical pion mass of approximately 400 MeV.
This paper presents the first lattice QCD calculation of the electromagnetic form factors for the tetraquark, providing evidence that its internal structure comprises a compact heavy diquark and a light antidiquark.
This paper presents the RBC/UKQCD collaborations' current status on calculating isospin breaking corrections to the hadronic vacuum polarization using stochastic coordinate sampling to efficiently construct all necessary Wick contractions and employing various lattice QED formulations to better estimate finite-volume uncertainties.
This paper presents a systematic QCD sum-rule analysis of charged kaons in hot and dense matter, deriving their in-medium masses and decay constants to reveal a significant mass splitting driven by baryonic interactions and identifying a critical density threshold that signals the onset of chiral symmetry restoration.
Using auxiliary-field quantum Monte Carlo simulations, this study provides precise thermodynamic benchmarks for the strongly interacting two-dimensional Fermi gas, identifying signatures of a pseudogap regime where pairing correlations persist above the superfluid critical temperature.
This paper advances the quantum simulation of massive Thirring and Gross–Neveu models with arbitrary fermion flavors by analyzing their gate complexity, classifying their dynamical Lie algebras, and successfully preparing their ground states using an adaptive-variational quantum imaginary time algorithm.
This paper demonstrates that the ground states of quantum link models with dynamical matter in and dimensions naturally reside in a specific Gauss law sector that is free of the fermion sign problem, a property that enables efficient simulation via a meron cluster algorithm.
