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 new non-perturbative results on the meson spectrum and low-energy constants in large- QCD, derived from lattice Monte Carlo simulations of the Twisted Eguchi-Kawai model up to combined with standard finite- data.
Using first-principles lattice simulations of SU(3) Yang-Mills theory in Rindler spacetime, this study demonstrates that weak acceleration induces a spatially inhomogeneous confinement-deconfinement phase transition where distinct phases coexist, with a phase boundary consistent with theoretical predictions and a critical temperature matching that of non-accelerated gluodynamics.
Using anisotropic clover fermion discretization on 16 flavor QCD ensembles, the authors present a non-perturbative renormalization framework that accurately determines the bottom quark mass, the full S-wave bottomonium spectrum, and decay constants with uncertainties of 0.1% or less, even on lattices with relatively coarse spacing.
This paper investigates the relationship between effective degrees of freedom and the trace anomaly within the hadron resonance gas model, demonstrating that applying a convexity-based "c-theorem like" condition yields a limiting temperature consistent with lattice QCD predictions and the critical point, whereas a non-decreasing condition results in a significantly higher temperature.
This paper demonstrates that the two-dimensional Rokhsar-Kivelson lattice gauge model intrinsically hosts exact stabilizer eigenstates known as sublattice scars, establishing a direct link between lattice gauge constraints, quantum many-body scarring, and stabilizer quantum information theory.
Addressing the breakdown of Bloch's theorem in spatially varying composites, this paper establishes a foundational ab initio quantum theoretical framework for functionally graded materials that derives effective field equations for modulated Bloch states, revealing non-tensorial electromagnetic properties and enabling the predictive design of optimized electronic devices such as graded p-n junctions.
This paper demonstrates that by renormalizing the Dirac field in curved spacetime, the metric's temporal and spatial gradients naturally induce non-Hermitian phenomena—specifically nonunitary gain/loss and the non-Hermitian skin effect—thereby establishing a unified geometric framework that links spacetime deformations to non-Hermitian phases of matter.
This paper computes the hadronic vacuum polarization to three loops in two-flavor chiral perturbation theory, identifying six elliptic master integrals and establishing previously unknown relations essential for renormalizability to provide a foundation for phenomenological and lattice QCD applications.
This paper presents a lattice QCD calculation of low-energy -wave interactions between doubly charmed baryons and Goldstone bosons, revealing an attractive interaction with a virtual state pole in the channel while the other studied channels are repulsive.
This paper presents a method for calculating entanglement entropy in models at finite density by integrating the replica trick with worm algorithm Monte Carlo simulations, showcasing initial results for the 3D nonlinear model.
