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.

By employing a expansion in holographic models of confining gauge theories, the authors demonstrate that the maximum supercooling in thermal confinement transitions is universally suppressed by and determined by the speed of sound in the deconfined phase, independent of specific scalar potential details.
This paper presents a novel Padé-based algorithm that reinterprets Froissart doublets as diagnostic tools to iteratively identify and remove data inconsistencies, thereby enabling the reliable reconstruction of a function's analytic structure from finite datasets without requiring a specific model for the errors.
Using lattice theory as a proof of principle, this paper demonstrates that classical field simulations can effectively model particle production and subsequent equilibration in nonequilibrium quantum field dynamics, establishing a scalable pathway for future quantum computing applications in studying pre-equilibrium systems like the early Universe and heavy-ion collisions.
This paper utilizes model-independent low-energy theorems derived from chiral symmetry breaking to compute pion matrix elements and decay rates in a uniform magnetic field, comparing these results with chiral perturbation theory, lattice QCD, and the Nambu-Jona-Lasinio model to highlight significant tensions between the latter and low-energy QCD.
This paper establishes a self-consistent framework using relativistic QCD Sum Rules to simultaneously determine heavy-quark masses and their Hadronic Vacuum Polarization contributions to the muon anomalous magnetic moment, leveraging their intrinsic anticorrelation to achieve unprecedented phenomenological precision and provide a direct diagnostic for residual theoretical uncertainties.
Using chiral perturbation theory with dimensional regularization, this paper analyzes the impact of a localized, inhomogeneous magnetic field on the QCD vacuum at zero temperature, demonstrating that equilibrium observables and induced vacuum currents can be precisely determined at next-to-leading order without undetermined parameters, thereby revealing the nonlocal spatial structure of the magnetized vacuum beyond locally constant approximations.
This paper demonstrates that noncommutative "fuzzy" geometry serves as a powerful nonperturbative tool for spectroscopy in massive quantum field theories, successfully reproducing known meson masses in the 1D Ising model and revealing bound-state evolution and glueball-like features during the crossover to 2D.
This paper proposes and validates a method for extracting Hamiltonian energy eigenvalues from quantum-generated real-time correlators using the generalized eigenvalue problem, demonstrating through simulations and hardware tests that it is substantially more efficient than Fourier transform-based approaches.
This paper demonstrates that the operator structure of the large- chiral Lagrangian induces specific correlations among low-energy constants (such as , , and ), necessitating a reinterpretation of phenomenological and lattice results in terms of these correlated directions to ensure consistent precision studies in U(3) chiral perturbation theory.
This paper numerically investigates chiral symmetry restoration in holographic QCD using a Born-Infeld black hole background, revealing that while the nonlinear electrodynamics parameter stabilizes the chirally broken phase and shifts transition temperatures, it does not alter the transition order or generate a critical endpoint within the studied range.
