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 three sample-efficient classical shadow protocols for lattice gauge theory that leverage gauge symmetry to achieve exponential improvements in sample complexity over symmetry-agnostic methods, offering a blueprint for simulating more general lattice gauge models.
This paper introduces and validates a formally correct machine-learning-based global proposal mechanism for Monte Carlo sampling in SU(2) lattice gauge theory, demonstrating its ability to reproduce target ensembles and achieve modest efficiency gains in hybrid configurations while serving as a proof-of-principle foundation for future extensions to larger lattices and non-Abelian theories.
This paper proposes a novel framework modeling topological phases of matter by embedding code-based Narain conformal field theories into critical lattice quantum field theory, utilizing Lie algebra constructions to demonstrate emergent fermionic excitations with Dirac cones characteristic of the Haldane model.
This paper combines lattice QCD, effective field theories, and multimessenger constraints to model first-order QCD phase transitions in neutron stars, predicting distinctive signatures such as twin star branches and delayed gravitational-wave frequency shifts that, while marginally consistent with current data, offer testable predictions for next-generation detectors like the Einstein Telescope.
Motivated by recent HAL QCD simulations, this study employs a first-principles few-body framework to predict the existence of deeply and moderately bound -mesic nuclei (, , and ), demonstrating that strong short-range attraction in the channel is the key binding mechanism.
This paper argues that CP is conserved in strong interactions because topological quantization arises from taking the infinite spacetime volume limit before summing over topological sectors, a reasoning the authors demonstrate is consistent with steepest-descent path integral constructions and robust against various objections regarding theta-parameters and instanton approximations.
This paper demonstrates that in a 2D quantum Ising model, specific initial-state entanglement—not merely entanglement entropy—suppresses false-vacuum decay to stabilize system-size macroscopic clusters, thereby offering a passive mechanism for preserving global information in quantum many-body systems.
This paper employs a finite-volume formalism incorporating left-hand-cut effects from one-pion exchange to analyze lattice QCD data at the SU(3)-symmetric point, revealing that these effects produce a mild but statistically significant impact on the binding energy of the -dibaryon compared to standard Lüscher quantization methods.
This paper proposes a novel inverse problem framework for calculating non-perturbative QCD quantities by deriving them from high-energy perturbative inputs, utilizing Tikhonov regularization to stabilize the inherently ill-posed problem and demonstrating its efficacy through toy models.
This paper investigates a (1+1)D lattice gauge theory with dynamical matter and static background charges, revealing a dynamical phase diagram that includes ergodic, nonthermal fragmented, and disorder-free many-body localized regimes, where the latter preserves spatial inhomogeneities through superpositions of gauge superselection sectors.
