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.
Below are the latest papers in High Energy Physics – Lattice, curated directly from arXiv and ready for you to explore.
This paper investigates the analytic structure of the QCD phase diagram by treating temperature as a complex variable, combining universal critical scaling, effective models, and lattice-QCD data to locate the nearest Yang-Lee edge singularities and establish a consistency test for critical-point searches via the relationship between complex-temperature and complex-chemical-potential trajectories.
This paper introduces three families of globally smooth, analytically invertible scalar bijections and a novel radial flow architecture that together overcome the expressivity and stability trade-offs of existing normalizing flows, achieving superior performance with significantly fewer parameters on both standard benchmarks and complex physics problems like lattice field theory.
Using the Grassmann corner transfer matrix renormalization group, this study maps the phase diagram of the single-flavor Gross--Neveu--Wilson model, identifying distinct universality classes for phase boundaries via entanglement entropy scaling and demonstrating that the Aoki phase does not persist in the strong-coupling regime.
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 utilizes tensor networks to calculate the gauge-invariant entanglement entropy and stabilizer Rényi entropy of the ground state in (1+1)-dimensional SU(2) lattice gauge theory, revealing a critical crossover point where the system transitions from a high-magic regime to a low-magic regime, thereby offering new insights into the interplay between non-stabilizerness and entanglement relevant for quantum simulations.
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.
This study employs QCD sum rules with advanced computational techniques to investigate and dibaryons, revealing that while scalar states are lighter than tensor ones, the charm system likely remains unbound above its threshold whereas the bottom system may form bound states in the scheme.
