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 presents a systematic QCD sum-rule analysis of charged kaons in hot and dense matter, deriving their in-medium masses and decay constants to reveal a significant mass splitting driven by baryonic interactions and identifying a critical density threshold that signals the onset of chiral symmetry restoration.
Using auxiliary-field quantum Monte Carlo simulations, this study provides precise thermodynamic benchmarks for the strongly interacting two-dimensional Fermi gas, identifying signatures of a pseudogap regime where pairing correlations persist above the superfluid critical temperature.
This paper advances the quantum simulation of massive Thirring and Gross–Neveu models with arbitrary fermion flavors by analyzing their gate complexity, classifying their dynamical Lie algebras, and successfully preparing their ground states using an adaptive-variational quantum imaginary time algorithm.
This paper demonstrates that the ground states of quantum link models with dynamical matter in and dimensions naturally reside in a specific Gauss law sector that is free of the fermion sign problem, a property that enables efficient simulation via a meron cluster algorithm.
This paper introduces sign-problem-free qubit-regularized lattice gauge theories in the monomer–dimer–tensor-network basis that successfully reproduce the confined and deconfined phases and universality classes of conventional SU(N) theories, suggesting a viable nonperturbative pathway to defining continuum limits for Yang–Mills theory.
This paper presents a comprehensive lattice formulation of Dirac operator indices using -theory and spectral flow, which overcomes the limitations of the overlap Dirac operator by enabling applications to manifolds with curved boundaries and defining mod-2 indices in both even and odd dimensions.
This paper presents a comprehensive analysis of bottom-charmed meson states using the inverse matrix QCD sum rules formalism, which successfully reconstructs hadronic spectral densities from first principles to determine masses and decay constants that align with experimental data while offering improved numerical stability and reduced systematic uncertainties compared to standard methods.
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 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.
