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 presents efficient methods for preparing approximate ground states of SU(3) lattice gauge theory on quantum hardware by refining irrep truncation via energy density, developing perturbation-guided ansatz circuits, and releasing open-source tools for circuit construction and Clebsch-Gordan coefficient calculations.
This paper calculates the gauge-invariant entanglement entropy and stabilizer Rényi entropy of the ground state in 1+1-dimensional SU(2) lattice gauge theory using tensor networks, revealing a crossover point where the system transitions from a magic-rich regime to one with less magic.
This paper refutes Matteo Giordano's comment by demonstrating that the proposed counterexamples violate the fundamental QCD assumption of analyticity in the squared quark mass at high temperatures and by identifying a technical error in the critique, thereby upholding the validity of the authors' original arguments regarding chiral symmetry restoration and the axial U(1) anomaly.
This paper introduces a Clifford-augmented Grassmann matrix product state (CAGMPS) framework combined with a DMRG algorithm that utilizes local Clifford disentanglers to systematically suppress bipartite entanglement and improve ground-state energy accuracy for strongly correlated fermionic systems.
This paper proposes a forward-mode automatic differentiation framework for tensor renormalization group methods that offers significantly higher accuracy in calculating thermodynamic quantities compared to conventional impurity methods, while establishing a theoretical link between the two approaches and providing practical procedures for extracting critical exponents in both two and three dimensions.
Using lattice QCD simulations with improved actions, the study demonstrates that localized low-lying Dirac eigenmodes emerge at a temperature of 150–160 MeV, placing the onset of this localization phenomenon firmly within the chiral crossover region.
Using QCD sum rules and the iterative dispersion relation method, this study investigates the and dibaryons, finding that the scalar states are lighter than their tensor counterparts and that while the bottom system may form bound states in the scheme, both systems are predicted to be much heavier in the on-shell scheme.
This paper utilizes the LASSO machine learning method to analyze recent LQCD data within three-flavor NLO Chiral Perturbation Theory, precisely determining the quark mass dependence of pseudoscalar meson decay constants up to 780 MeV and applying these results to predict octet baryon masses in the SU(3) limit.
This paper proposes an analog quantum simulation of chiral magnetic dynamics using ultracold atoms in optical superlattices, demonstrating that the massive Schwinger model can be mapped to the Rice-Mele model to robustly probe non-equilibrium vector current behavior and chirality injection through realistic, noise-resilient protocols.
This paper utilizes QCD light-cone sum rules to calculate the magnetic dipole, electric quadrupole, and magnetic octupole moments of , , and molecular pentaquarks, establishing a hierarchy of magnetic moments and spatial deformation signatures that serve as critical benchmarks for distinguishing their molecular structure from compact exotic hadron models.
