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.

The Extended Twisted Mass Collaboration presents an updated determination of the leading-order hadronic vacuum polarisation contribution to the muon anomalous magnetic moment in isospin-symmetric QCD, utilizing five gauge ensembles with near-physical pion masses and employing two distinct valence-quark regularisations to calculate both isovector and isoscalar components.
This paper introduces a novel generative architecture based on physics-informed kernels that resolves sign problems and enables efficient sampling for systems with complex probability distributions by mapping them to sign-problem-free manifolds, demonstrating its effectiveness in zero-dimensional field theories and real-time quantum-mechanical evolution.
This paper establishes the precise mathematical relations and necessary edge-effect corrections required to ensure the mutual equivalence of window quantities for the hadronic vacuum polarization contribution to the muon anomalous magnetic moment across spacelike and timelike domains, thereby enabling hybrid assessments using diverse data sources like lattice QCD, MUonE, and -ratio measurements.
Using matrix product state simulations, this paper reveals that doping the Gross-Neveu-Wilson model induces exotic inhomogeneous phases, including topological crystals and soliton lattices driven by Hilbert-space fragmentation, as well as chiral spirals, thereby demonstrating the rich finite-density landscape of lattice field theories and motivating future quantum simulations.
This paper demonstrates that while leading-order lattice chiral effective theory successfully reproduces finite-volume energy spectra in the isospin channel, it fails in the channel by predicting a spurious resonance absent in lattice QCD, suggesting that the theory does not converge well with a naive lattice regularization.
Using lattice Yang-Mills simulations, the paper demonstrates that a test quark near a reflective chromometallic boundary in the QCD confinement phase forms a partially confined "quarkiton" state bound by an attractive Cornell-type potential with reduced string tension, analogous to surface excitons in condensed matter physics.
This paper introduces a position-space sampling method within the distillation framework to efficiently compute local multiquark operators, demonstrating that including local tetraquark operators significantly alters the extracted finite-volume spectrum and scattering phase shifts of the state.
This paper presents a high-precision lattice QCD determination of the nucleon iso-vector scalar and tensor charges at the physical point by employing a novel "blending" method to suppress excited state contamination across 15 ensembles, yielding the most accurate predictions to date with comprehensive systematic error analysis.
This paper introduces a non-perturbative lattice Monte Carlo method in imaginary time, featuring a novel sampling technique to overcome false vacuum suppression and a new Fermi's Golden Rule-like formula, to accurately calculate quantum tunneling rates, as validated by reproducing one-dimensional Schrödinger equation results.
This paper introduces a real-valued transfer matrix optimization to the generalized combinatorial Feynman--Vdovichenko method, enabling the calculation of critical temperatures for Sierpinski carpets up to generation and yielding the most accurate estimate to date for the canonical case.
