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 a concrete lattice realization of the equation of motion flow for -dimensional chiral gauge theories on a disk boundary, demonstrating how coupling the flow gauge field to fermions enables the mechanism of anomaly inflow and cancellation.
This paper implements and analyzes two distinct gauge field flow constructions—gradient flow decoupling and equation-of-motion (EOM) flow—for chiral gauge theories formulated with domain wall fermions on a lattice slab, demonstrating how these methods successfully preserve current conservation and realize anomaly inflow in the presence of background gauge fields.
This paper investigates five symmetry-preserving Hamiltonian variational ansatzes for the d lattice gauge theory, demonstrating through numerical analysis of dynamical Lie algebras and quantum Fisher information matrices that overparametrization eliminates local minima and accelerates VQE convergence, thereby advancing the theoretical understanding of scalable quantum circuit design.
Using four-dimensional causal dynamical triangulation simulations, this paper presents evidence for the existence of massive geons—self-bound graviton states—through curvature-curvature correlators, suggesting potential implications for dark matter and primordial black holes while noting a connection between their mass and the expansion phase of the de Sitter universe.
This paper extends the RI/SMOM renormalization scheme to semi-leptonic operators by utilizing chirally symmetric massless QCD to relate them to protected vector currents, demonstrating the equivalence of a new family of projectors with recent results relevant for calculating Wilson coefficients.
This paper proposes a feasible scheme using ultracold atoms in a periodically driven 3D optical Raman lattice to realize unpaired Weyl points with tunable net chirality, thereby enabling the observation of the chiral magnetic effect and providing a controllable platform for exploring nonequilibrium topological phenomena.
This paper proposes a photonic analog quantum simulation scheme based on the Jaynes-Cummings-Hubbard model to replicate the real-time dynamics of a (1+1)-dimensional Lattice Gauge Theory with dynamical matter by mapping polaritonic hopping in cavity arrays onto a spin-1/2 Quantum Link Model.
This paper analyzes lattice QCD data using unitarized chiral perturbation theory to reveal that the experimental resonance corresponds to a two-pole structure, where a lower pole () behaves like the meson and an upper pole relates to the representation, with their distinct behaviors across chiral trajectories offering new insights into their underlying quark-gluon dynamics.
This paper presents a comprehensive finite-volume calculation of pion-pion scattering within Chiral Perturbation Theory and the Inverse Amplitude Method that incorporates discretization effects across all scattering channels and group representations, revealing significant corrections for small volumes () that improve the accuracy of energy level and phase-shift determinations compared to previous analyses.
This paper employs thermal tensor networks to numerically verify the Svetitsky-Yaffe conjecture for the deconfinement transitions of (2+1)-dimensional lattice gauge theories () by extracting universal CFT data, while also identifying an intermediate phase with emergent U(1) symmetry in the case and determining zero-temperature critical couplings.
