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 constructs 3+1D and 2+1D Hamiltonian lattice models for Weyl fermions and Dirac cones that evade no-go theorems by utilizing exact, not-on-site chiral symmetries—specifically a Ginsparg-Wilson analog and an Onsager algebra—to protect gaplessness and generate global anomalies even in the absence of crystalline translations.
This paper introduces a generalized definition of isothermal compressibility in (2+1)-flavor QCD based on conserved charge fluctuations, presenting lattice results that align with hadron resonance gas models and heavy-ion collision data while demonstrating that the compressibility on the pseudo-critical line closely resembles that of an ideal gas.
This study demonstrates that applying the Medium Separation Scheme (MSS) alongside Magnetic Field Independent Regularization (MFIR) to the Nambu--Jona-Lasinio model of magnetized two-flavor color superconducting quark matter eliminates unphysical oscillations and ensures positive magnetization, thereby correcting artifacts found in traditional approaches that fail to properly separate medium effects from vacuum contributions.
This paper investigates the Casimir effect for lattice fermions under various boundary conditions, demonstrating that while naive fermions exhibit lattice-size-dependent oscillations, all formulations—including naive, Wilson, and overlap fermions—converge to the correct continuum limit, thereby confirming their universality in reproducing the Casimir effect.
This paper presents lattice QCD calculations of light-nuclei masses across various quark masses to establish first-principles constraints on nuclear interactions and reveals that, while quark-mass contributions to binding energy are small and additive, the dominant contribution arises from the gluonic component via the QCD trace anomaly.
This study utilizes tensor network calculations to demonstrate that in D lattice gauge theory, the late-time bipartite entanglement entropy remains independent of system size under both local and non-local measurements, indicating the absence of a measurement-induced phase transition in the no-click limit.
This paper addresses the challenges of extracting scattering amplitudes from staggered lattice QCD by proposing two complementary approaches: calculating one-loop amplitudes using Rooted Staggered Chiral Perturbation Theory to verify quantization conditions, and generalizing the Lüscher formalism to explicitly incorporate taste-splitting and fourth-rooting effects.
This paper proposes a first-principles strategy to extend lattice QCD calculations of inclusive hadronic decays to include QED and isospin-breaking effects, presenting preliminary results within the RM123 framework to ultimately improve the determination of the CKM matrix element .
This paper refutes the proposal that orbifold lattices offer an exponential speedup for quantum simulations of Yang--Mills theory by demonstrating through analytical and numerical evidence that compounding hidden costs, including severe Trotter overhead and gauge-violating dynamics, render the approach orders of magnitude more expensive than existing alternatives.
This paper presents the first non-perturbative determination of the model-independent QCD contribution to the axion-photon coupling using continuum extrapolated lattice simulations, yielding a precise value that enables updated constraints on axion models to guide future experimental strategies.
