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 presents a parameter-free method to determine the chiral phase transition temperature and critical exponent in (2+1)-flavor QCD by constructing ratios of an improved, renormalized order parameter, with initial numerical results obtained on lattices using staggered fermions.
This paper presents the four-loop renormalization of generalized 3-quark operators in the MSbar scheme, determining the anomalous dimensions of the four core operators for nucleon matrix elements and analyzing their critical exponents within the conformal window via the Banks-Zaks expansion.
This paper demonstrates that a triangular Rydberg array can serve as an analog quantum simulator for (2+1)D U(1) lattice gauge theory, naturally realizing string roughening phenomena such as logarithmic width growth and the Lüscher correction, while also enabling the observation of real-time string fluctuations and breaking dynamics.
This study presents an algorithm for the automatic structural search of tensor network states, including entanglement renormalization, which optimizes local structures based on variational energy to improve accuracy in representing non-uniform entangled states, particularly when initialized with existing design methods like the strong disordered renormalization group.
Using lattice QCD with physical quark masses and Asqtad-improved staggered fermions, this study computes the -wave scattering length and effective range parameters, finding results that align with both next-to-leading order chiral perturbation theory predictions and experimental measurements.
This paper proposes a fine-grained parallel tensor network design utilizing FPGAs and a quad-tile partitioning strategy to drastically reduce the computational cost scaling of iTEBD and HOTRG algorithms from to and from to , respectively, thereby offering a scalable hardware solution for large-scale quantum many-body calculations.
This paper demonstrates that spontaneous parity breaking serves as a systematic guiding principle for predicting and rationalizing the emergence of nontrivial phases, such as intermediate-spin parity-broken states and bilayer supersolids, in frustrated quantum antiferromagnets on triangular lattices, a conclusion validated by large-scale tensor network calculations.
This paper demonstrates through linear stability analysis and lattice QCD simulations that Hessian-free variants of force-gradient integrators offer comparable stability to conventional methods while enabling more efficient computations for interacting field theories.
These lecture notes provide a graduate-level introduction to the strong CP problem and QCD axion physics from an effective field theory perspective, covering the construction of chiral EFT, the derivation of CP-odd observables, generalizations to various gauge theories, critiques of alternative solutions, and the standard Peccei-Quinn mechanism.
This paper reassesses the feasibility of using coherent state variational methods for large gauge theories by introducing a new implementation applicable to SU() lattice gauge theories with or without fermions, and presents initial results for Hamiltonian Yang-Mills theory on an infinite two-dimensional spatial lattice.
