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 reports the emergence of metastable confinement and resonant string breaking in U(1) lattice gauge theories simulated by Rydberg atom arrays, demonstrating how the competition between string tension and four-Fermi coupling, along with Floquet-driven sideband resonances, enables controlled melting of initial string states.
This paper presents a lattice study of the one-flavor $SU(4)$ Hyper Stealth Dark Matter theory, demonstrating that dynamical dark sea quarks reduce the interface tension of the confinement transition and consequently suppress the resulting gravitational wave amplitude.
Using first-principles lattice simulations, this paper reveals a novel spatially inhomogeneous phase in rotating gluon plasma where confining and deconfining regions coexist in thermal equilibrium, with the deconfined phase localized near the rotation axis and the confined phase at the periphery, a structure explained by action anisotropy in the curved co-rotating background rather than the standard Tolman-Ehrenfest law.
This paper presents a finite-size scaling analysis of the chiral order parameter in (2+1)-flavor QCD using HISQ lattice data, demonstrating that infinite-volume extrapolated results align with expected scaling behavior while quantifying finite-size deviations to improve the precision of chiral phase transition temperature determinations.
Using large-scale Monte Carlo simulations, this study demonstrates that a 3D lattice Gross-Neveu model with two four-fermion interactions exhibits a multicritical point where the direct transition to a symmetric massive phase splits into two successive transitions (Gross-Neveu and XY universality classes) separated by a symmetry-broken phase, thereby unifying conventional and unconventional fermion mass generation mechanisms.
This paper proposes a shallow-circuit fermionic scattering state preparation method that approximates wave packets via spatial localization to reduce circuit depth by nearly half while preserving anti-commutation relations, demonstrating its efficacy through MPS simulations and successful implementation on IonQ's Forte 1 NISQ hardware.
This paper presents a unified theoretical description of experimental data for decays into and accompanied by pion or kaon pairs, utilizing unitary and analytic final-state interactions to reveal universal coupling patterns, a distinct non-charmonium nature for the , and the significant role of the resonance while predicting related branching fraction ratios and invariant mass distributions.
This paper reveals fundamental trade-offs in Gauss's law-based quantum error correction for 1+1D lattice QED, demonstrating that while it can reduce qubit overhead and offer lower single-round error rates, it imposes strict constraints on electric field configurations and ultimately leads to faster decoherence to mixed states compared to universal codes under repeated error correction cycles.
This paper investigates chiral symmetry restoration by analyzing quark-antiquark distances through confinement potentials and hadronic cross sections, demonstrating that the light-front QCD mass scale parameter can control inter-quark separation to potentially allow free quarks even within the confinement regime.
The authors propose a modified stochastic quantization method using discrete fictitious time and weighted noise averaging that recovers quantum field theory correlation functions in the large time limit without requiring a continuum limit, a result they validate through perturbative and numerical tests in a zero-dimensional model.
