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 an efficient block encoding algorithm for the plaquette operator in the irreducible representation basis of non-Abelian lattice gauge theories, overcoming previous scaling limitations by leveraging matrix element factorization, classical precomputation, and quantum oracles.
This paper proposes a Z-transform framework that reinterprets the fermion doubling problem as an aliasing phenomenon, leading to the development of finite-range lattice momentum operators that suppress ghost modes through least-squares spectral approximation rather than symmetry-breaking terms or nonlocal derivatives.
This paper extends the recently established framework of understanding dualities through finite-depth quantum circuit gauging and disentangling to continuum field theories, demonstrating its efficacy by re-deriving T-duality and bosonization.
This paper introduces a generalized stochastic quantization framework based on jump-diffusion processes (Lévy flights) to overcome topological freezing and restore ergodicity in Euclidean lattice field theories, specifically demonstrating its effectiveness in 2d U(1) gauge theory.
This paper constructs explicit electric, magnetic, and dyonic 1-form symmetry operators for non-Abelian quantum double lattice models, demonstrating that they form a non-invertible fusion algebra that provides a complete microscopic diagnostic for the topological Hilbert space and characterizes ground states as spontaneously broken non-invertible 1-form symmetry phases.
This paper validates the configurational temperature estimator as a robust internal diagnostic tool for Monte Carlo and Langevin simulations of the 3D XY model with an imaginary chemical potential, demonstrating its effectiveness in checking algorithmic correctness and thermalization while identifying finite-size effects as the primary source of deviations in the ordered phase.
This chapter outlines the contemporary theoretical understanding of exotic hadrons containing essential gluonic excitations, specifically glueballs and hybrids, while discussing the challenges involved in definitively identifying these states within the experimental hadron spectrum.
This paper presents a hybrid classical-quantum strategy to enhance the efficiency of Hamiltonian truncation for quantum field theories by introducing an integer partition-based basis generation, symmetry-aware sparse matrix construction, and quantum Krylov diagonalization, demonstrating significant computational gains in two-dimensional scalar and models.
This paper presents the first computation of the subleading twist correction from the three-particle -meson distribution amplitude at next-to-leading order using soft-collinear effective theory, thereby completing the leading-power factorization analysis and enabling improved field-theoretic predictions for electroweak penguin decays.
This paper investigates whether the spectral directions triggering the first Gribov horizon are necessarily accessible to the sources in Zwanziger's horizon function by analyzing radial SU(2) hedgehog backgrounds in three and four Euclidean dimensions, revealing potential "blind spots" where critical subspaces may remain undetected due to degeneracy or domain constraints.
