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.
Using QCD sum rules with the iterative dispersion relation method to handle complex loop diagrams, this study predicts that scalar and dibaryons lie lower in energy than their tensor counterparts, with the former appearing as a resonance just above the threshold and the latter potentially forming bound states.
This paper reveals fundamental trade-offs in Gauss's law-based quantum error correction for 1+1D lattice QED, demonstrating that while it can reduce qubit overhead and offer lower single-round error rates, it imposes strict constraints on electric field configurations and ultimately leads to faster decoherence to mixed states compared to universal codes under repeated error correction cycles.
This paper investigates chiral symmetry restoration by analyzing quark-antiquark distances through confinement potentials and hadronic cross sections, demonstrating that the light-front QCD mass scale parameter can control inter-quark separation to potentially allow free quarks even within the confinement regime.
The authors propose a modified stochastic quantization method using discrete fictitious time and weighted noise averaging that recovers quantum field theory correlation functions in the large time limit without requiring a continuum limit, a result they validate through perturbative and numerical tests in a zero-dimensional model.
This paper proposes an efficient quantum algorithm for real-time simulation of Quantum Electrodynamics in the Coulomb gauge using a position-space field basis, which eliminates the need for constraint enforcement and reduces gate costs by approximately eight orders of magnitude compared to previous momentum-space occupation basis approaches.
This study demonstrates that sparse modeling can successfully reconstruct charmonium resonance peaks from lattice QCD data at finite temperatures, yielding results qualitatively consistent with the maximum entropy method, though it struggles to resolve transport peaks without additional assumptions.
This paper presents a method for automatically generating Hybrid Monte Carlo forces in lattice gauge theory by applying reverse-mode automatic differentiation directly to optimized LLVM intermediate representation, enabling a single-source workflow that produces performance-portable, high-performance force implementations for both CPU and GPU backends without the need for manual derivation.
This study demonstrates that incorporating local tetraquark operators into a variational analysis using Wilson-clover fermions and a novel position-space sampling method significantly alters the finite-volume energy spectrum and resulting scattering phase shifts for the tetraquark.
This lattice simulation study demonstrates that weak acceleration in gluodynamics transforms the standard finite-temperature confinement-deconfinement phase transition into a spatial crossover, allowing coexisting phases that follow the Tolman-Ehrenfest law and suggesting similar phenomena may occur near black hole horizons.
This paper provides a guide to Trotter-Suzuki schemes and introduces new, optimized higher-order decompositions that significantly reduce gate counts for simulating lattice field theories, as demonstrated on the Heisenberg model.
