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 introduces a robust multiple shooting method for accurately determining Lefschetz thimble intersection numbers in multivariable systems, enabling stable real-time path integral evaluations and offering new insights into oscillatory integrals in physics and mathematics.
This paper employs a nonperturbative Hamiltonian framework using Daubechies wavelets in momentum space to analyze dimensional theory, successfully demonstrating the emergence of a strong-coupling phase transition in the sector.
This paper proposes a scalable superconducting-circuit architecture that utilizes the intrinsic infinite-dimensional Hilbert space of rotor variables to realize compact U(1) lattice gauge theory with exact Gauss's law and emergent gauge dynamics, offering a continuous-variable platform for analog quantum simulation without the need for Hilbert-space truncation or auxiliary stabilizers.
This paper introduces finite Gaussian assistance protocols and a multimode conic metric framework to optimize spacelike vacuum entanglement, yielding the highest known lower bound for Gaussian entanglement of assistance and the lowest known upper bound for Gaussian entanglement of formation in free scalar fields.
This paper offers a pedagogical introduction to the Silver Blaze problem in QCD, which addresses the paradox of why physical observables remain unchanged below a critical chemical potential despite the chemical potential altering the Dirac operator's eigenvalues, by analyzing the behavior of functional integrals and the role of phase cancellations in gauge configurations.
Using anisotropic FASTSUM Generation 3 ensembles, this study proposes a new method to probe symmetry restoration via mesonic correlators and finds that the symmetry is effectively restored at approximately 320 MeV, a temperature significantly higher than the chiral transition temperature of 180 MeV.
This paper utilizes Bayesian thermal analysis of hadron yields from STAR Ru+Ru and Zr+Zr isobar collisions to precisely extract chemical potential differentials in the QCD phase diagram, thereby validating these collisions as a high-precision probe for four-dimensional QCD thermodynamics against lattice-QCD and Chiral Mean Field model predictions.
This paper resolves the ambiguity in mixing between nonlocal gluon and quark bilinear operators by demonstrating that dimensional regularization provides a consistent prescription for handling singularities at zero separation, ensuring agreement between coordinate and momentum space results and compatibility with lattice QCD extractions.
This paper employs gauge/string duality to analyze the string configurations and Born-Oppenheimer potentials of a system, revealing that its ground state can manifest as a hadronic molecule, a tetraquark, or a superposition depending on geometry, while also deriving asymptotic energy expressions and demonstrating string tension universality for multiquark configurations.
This paper investigates a dark matter model based on a symplectic gauge group, analyzing its thermodynamic properties near the confinement phase transition and exploring the resulting gravitational-wave production and relic abundances in the early universe.
