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.
Below are the latest papers in High Energy Physics – Lattice, curated directly from arXiv and ready for you to explore.
This paper calculates the leading-order mixed-action chiral perturbation theory constant using -flavor lattice ensembles, revealing that the fermion action dominates the results while the gauge action has a measurable secondary effect and charm quark loops are negligible.
This paper presents the first lattice calculation of a two-to-two particle matrix element using pionless effective field theory to demonstrate that while finite-volume formalism is unnecessary for deep-bound states, it is critical for accurately determining the infinite-volume elastic form factors and charge radii of shallow-bound states like the deuteron.
This paper demonstrates that symmetry-twisted partition functions computed via the tensor renormalization group framework effectively detect spontaneous symmetry breaking in three-dimensional models, determine the BKT transition in two dimensions, and successfully identify phase transitions in generalized two-dimensional models.
This paper reviews recent advancements in tensor network renormalization group methods, highlighting their potential to overcome sign and complex action problems in lattice field theories and their growing application to studying quantum chromodynamics at finite temperature and density, as well as universal critical behaviors via conformal field theory insights.
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.
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.
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.
