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 demonstrates that the tensor renormalization group (TRG) method, when applied to symmetry-twisted partition functions, provides an efficient framework for detecting spontaneous symmetry breaking and accurately determining critical temperatures and exponents in the 2D Ising, 3D , and 2D (BKT) models.
This paper establishes that the criteria for Symmetric Mass Generation (SMG) are satisfied by the staggered fermion action in lattice QCD, proposes a renormalization group flow around the SMG transition based on numerical results, and identifies Goldstone tetraquark meson states as a phenomenological signature of the "type-II" SMG phase.
This paper demonstrates that within Yang-Mills-Proca theory, three static quarks generate a finite-energy color electric field with a Y-like spatial distribution and a toroidal color magnetic field, findings that align satisfactorily with lattice QCD calculations and are derived from a Lagrangian describing a spatially varying gluon condensate.
This paper demonstrates that enhanced sampling techniques, specifically Metadynamics with optimized bias potentials, effectively mitigate topological freezing in lattice gauge theories by reducing autocorrelation times, while also exploring strategies for accelerating bias buildup, extrapolating to larger volumes, and integrating orthogonal algorithmic improvements.
This paper investigates the symmetry structure of D staggered fermions, demonstrating that a specific one-link mass term preserving Onsager algebra symmetries generates a domain wall hosting massless Dirac fermions whose flavor symmetry and parity anomaly descend directly from the ultraviolet lattice Hamiltonian.
This paper investigates the entropic bottlenecks in a 2D apolar spin model that drive a crossover transition to a novel nematic phase characterized by unbound topological defects and itinerant para-nematic fluids, ultimately leading to a global nematic order at a lower temperature.
This paper reviews the current state of the QCD phase diagram by synthesizing insights from lattice simulations, effective field theories, and chiral models to reconstruct the full phase structure for physical quark flavors and constrain matter properties in neutron star cores.
This paper presents continuum-estimated (2+1)-flavor lattice QCD results demonstrating that the baryon-electric charge correlation serves as a sensitive magnetometer for strong magnetic fields, while also mapping the equation of state up to and constructing detector-compatible observables to bridge theoretical predictions with experimental heavy-ion collision data.
This paper investigates a quenched SU(2)U(1) lattice gauge Higgs theory coupled to a static vector-like fermion to identify new types of gauge-invariant electrically charged and neutral states that differ from previous constructions in their field dressing, revealing that while neutral states are significantly lighter, the charged spectrum contains at least two distinct particle states with different masses.
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.
