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 viable glueball dark matter candidate arising from a confined Yang-Mills sector coupled to the Standard Model via vector-like fermion portals, developing a non-perturbative effective field theory framework that predicts a steeply scaling spin-independent scattering cross-section () within the sensitivity reach of current and next-generation xenon direct-detection experiments.
This chapter introduces Quantum Chromodynamics at finite temperature and density by presenting the Euclidean path integral formulation, exploring thermal effective field theories, discussing the Equation of State as a key thermodynamic quantity, and concluding with an overview of the phase diagram for strongly interacting matter.
This paper employs renormalizable two- and three-flavor quark-meson-diquark models to analyze color superconductivity and pion condensation in dense quark matter, demonstrating that BCS gaps approach a constant and the speed of sound converges to the conformal limit at high chemical potentials while correctly accounting for global symmetry breaking and Goldstone boson counting.
Using fermion-bag Monte Carlo simulations, this study demonstrates that introducing a small nonzero four-fermion coupling () to a lattice fermion model qualitatively alters its phase diagram by splitting a single exotic symmetric mass generation transition into two distinct conventional transitions (Gross-Neveu and 3D XY) separated by an intermediate spontaneous symmetry breaking phase.
By combining advanced quantum Monte Carlo simulations with a novel loop estimator for Rényi entanglement entropy, this study demonstrates that an SU() generalization of the Heisenberg antiferromagnet in 1+1 dimensions exhibits weak first-order pseudocriticality driven by proximity to a complex conformal field theory, a finding that accurately recovers the real part of the complex central charge for and reinterprets the dimerized phase of the spin-1 chain as pseudocritical.
This paper details the computational strategy, simulations, and data analysis used to achieve a non-perturbative determination of the QCD Equation of State for three massless flavors at temperatures up to 165 GeV with approximately 1% accuracy, utilizing lines of constant physics and shifted boundary conditions to demonstrate the continued relevance of non-perturbative contributions even at the electroweak scale.
This paper introduces a reformulated electric basis and a local Krylov subspace truncation strategy for pure SU() lattice gauge theories, demonstrating that these efficient Hamiltonians remain consistent with traditional calculations at small couplings while reducing the computational resources required for quantum time evolution by 17–19 orders of magnitude.
This paper utilizes thermofield dynamics and the correspondence between low-energy excitations and Fisher zeros to analyze the quantum XY chain, revealing that "giant bubbles" of Fisher zeros near the gapless XX limit provide a characteristic energy scale that contradicts standard Luttinger liquid theory and links spectral weight transfer to unconventional gap behaviors.
This paper utilizes gauge/string duality to investigate string breaking in spatial Wilson loops, specifically analyzing the influence of light flavors on the pseudopotential and estimating the spatial string breaking distance for gauge theory across temperatures from 0 to .
This paper proposes and analyzes a trapped-ion quantum simulator for the Jackiw-Rebbi model that investigates the real-time dynamics of fractional charges by incorporating fermionic back-reaction and quantum fluctuations, revealing how these effects influence kink localization and scattering beyond fixed-background approximations.
