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.

These lectures provide a foundational introduction to dispersive methods in Standard Model phenomenology, utilizing analyticity and unitarity constraints to explore the hierarchical relationships between two-, three-, and four-point Green's functions across toy models, simple scalar theories, and QCD.
Using fermion-bag Monte Carlo simulations on large lattices, this study demonstrates that a multicritical point with enhanced symmetry emerges when symmetry-breaking parameters are tuned to zero, unifying traditional second-order transitions to reveal a direct second-order phase transition between massless and symmetric massive fermion phases.
Using fermion-bag Monte Carlo simulations, this study reveals that introducing a small nonzero four-fermion coupling () to a lattice fermion model with symmetric mass generation splits its single exotic quantum phase transition into two distinct conventional transitions (Gross-Neveu and 3D XY) separated by an intermediate spontaneous symmetry breaking phase.
This paper demonstrates that combining variational quantum eigensolver (VQE) state preparation with digital real-time evolution via Trotter-Suzuki decomposition effectively simulates the nonequilibrium dynamics of the (1+1)-dimensional Schwinger model under strong external electric fields, accurately reproducing key phenomena such as vacuum flips, boundary charge separation, and energy redistribution when benchmarked against exact diagonalization.
This paper solves the Roy equations for pion scattering at variable pion masses, utilizing chiral perturbation theory and lattice data to provide an accurate description of partial waves and resonance behavior that fully incorporates analyticity, unitarity, and crossing symmetry constraints.
This paper proposes and validates time-domain observables for extracting resonant scattering properties in pure lattice gauge theory by characterizing glueball dynamics via classical methods and demonstrating their feasibility on near-term quantum hardware through the simulation of a spectral toy model on a Quantinuum H2-2 device.
This paper demonstrates that diffusion models for lattice field theories can be trained without reference data by leveraging the target score identity and unnormalized probability densities, achieving performance comparable to traditional HMC-based training across various phases.
This paper presents the first Monte Carlo simulation of theory on Euclidean de Sitter space using a symmetry-preserving spectral lattice, confirming that the stochastic formalism correctly resums infrared divergences and revealing a de Sitter counterpart to the triviality mechanism that bounds the Higgs mass in flat space.
This paper demonstrates that Kähler-Dirac fermions coupled to gravity in Euclidean Dynamical Triangulations exhibit a taste-symmetry restoration in the continuum limit, where non-protected bound-state masses vanish as a power of the lattice spacing, analogous to the behavior of staggered fermions in flat-space lattice field theories.
This paper presents the first exploratory lattice QCD calculation of nucleon unpolarized, helicity, and transversity parton distribution functions using a novel Coulomb gauge boosted-correlator method within Large-Momentum Effective Theory, demonstrating that the approach yields results consistent with global analyses and phenomenology while highlighting specific challenges with excited-state contamination in imaginary matrix elements.
