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.

This paper proposes a family of quantum walks that eliminate fermion and pseudo-doublers while simulating the Dirac equation in the continuum limit by allowing a non-zero probability for the walker to remain at the same point, despite retaining a small number of non-Dirac low-energy solutions.
This paper introduces a new Monte Carlo estimator for flow fields that utilizes coupled Langevin noise to significantly mitigate statistical noise, thereby offering a robust method for addressing critical slowing down and signal-to-noise issues in lattice field theory while also generating unbiased training data for machine learning.
This paper argues that while classical lattice QCD suffices for stable hadron masses, quantum computers offer distinct utility for calculating resonance masses and nuclear properties by overcoming classical barriers like the Maiani-Testa theorem and signal-to-noise issues, a conclusion reached through extensive collaboration with the AI model Claude.
Using MILC's HISQ gauge ensembles with anisotropic Clover and -improved Wilson--Clover actions, this study investigates the tetraquark spectrum across varying quark masses and operator bases, employing a modified Lüscher method to address non-analyticity near the Left Hand Cut.
Using first-principles lattice simulations of SU(3) Yang-Mills theory in Rindler spacetime, this study demonstrates that weak acceleration induces a spatially inhomogeneous confinement-deconfinement phase transition where distinct phases coexist, with a phase boundary consistent with theoretical predictions and a critical temperature matching that of non-accelerated gluodynamics.
Using anisotropic clover fermion discretization on 16 flavor QCD ensembles, the authors present a non-perturbative renormalization framework that accurately determines the bottom quark mass, the full S-wave bottomonium spectrum, and decay constants with uncertainties of 0.1% or less, even on lattices with relatively coarse spacing.
This paper demonstrates that the two-dimensional Rokhsar-Kivelson lattice gauge model intrinsically hosts exact stabilizer eigenstates known as sublattice scars, establishing a direct link between lattice gauge constraints, quantum many-body scarring, and stabilizer quantum information theory.
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.
