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.

This paper introduces a reformulated electric basis and a local Krylov subspace truncation strategy for pure SU() lattice gauge theories, demonstrating that these efficient Hamiltonians remain consistent with traditional calculations at small couplings while reducing the computational resources required for quantum time evolution by 17–19 orders of magnitude.
This paper utilizes thermofield dynamics and the correspondence between low-energy excitations and Fisher zeros to analyze the quantum XY chain, revealing that "giant bubbles" of Fisher zeros near the gapless XX limit provide a characteristic energy scale that contradicts standard Luttinger liquid theory and links spectral weight transfer to unconventional gap behaviors.
This paper utilizes gauge/string duality to investigate string breaking in spatial Wilson loops, specifically analyzing the influence of light flavors on the pseudopotential and estimating the spatial string breaking distance for $SU(3)$ gauge theory across temperatures from 0 to .
This paper proposes and analyzes a trapped-ion quantum simulator for the Jackiw-Rebbi model that investigates the real-time dynamics of fractional charges by incorporating fermionic back-reaction and quantum fluctuations, revealing how these effects influence kink localization and scattering beyond fixed-background approximations.
Using the Born-Oppenheimer approximation within a dynamical diquark model, this study identifies the states as compact tetraquarks composed of axial-vector diquark pairs, supported by calculated root-mean-square radii significantly smaller than 1 fm.
This paper presents state-of-the-art theoretical predictions for the electromagnetic Dirac form factors of hyperons by computing next-to-leading-order QCD corrections within the hard-collinear factorization framework and combining them with lattice QCD-determined distribution amplitudes.
This paper derives a one-loop factorization formula connecting the leading-twist QCD light-cone distribution amplitude (LCDA) to the boosted HQET LCDA of the baryon by utilizing the method-of-regions to simplify perturbative matching calculations, thereby providing a crucial step toward future lattice QCD computations of heavy baryon LCDAs.
This paper presents a lattice QCD calculation of the nucleon's gluon momentum fraction using the gradient flow method with nonperturbative renormalization, yielding a final result of 0.482(35) at 2 GeV in the MS-scheme.
This paper demonstrates that half-precision (FP16) mixed-precision linear solvers with novel rescaling steps for Lattice QCD on A64FX processors achieve practical stability with only a minor increase in iteration count compared to double-precision methods.
This paper investigates how a modified domain-wall fermion operator accelerates iterative linear solvers in lattice QCD simulations by improving convergence rates while preserving the 4D solution, supported by eigenvalue analysis and implementation within the GPU-enabled Bridge++ code framework.
