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.

Exponential speedup in quantum simulation of Kogut-Susskind Hamiltonian via orbifold lattice

This paper demonstrates that the Kogut-Susskind Hamiltonian emerges as the infinite scalar mass limit of the more efficient orbifold lattice formulation, thereby resolving implementation challenges and enabling digital quantum simulations of SU(NN) Yang-Mills theories with exponential speedup over classical and prior quantum methods.

Analytic electromagnetic signatures of compact pentaquark structure: A multi-current QCD light-cone sum rules analysis of the PψsΛP_{\psi s}^{\Lambda} states

This paper employs multi-current QCD light-cone sum rules to derive distinct analytic electromagnetic signatures, specifically a light-quark magnetic moment ratio of μu/μd=2\mu_u/\mu_d = -2 and a vanishing charm contribution for specific currents, which serve as falsifiable tests to distinguish compact pentaquark structures from hadronic molecules.

Metamorphosis of fractional instantons on a twisted T4T^4 with a double-trace deformation: a numerical study

This paper employs numerical minimization of the lattice action in trace-deformed Yang-Mills theory on a twisted T4T^4 to demonstrate how fractional instantons, monopole-instantons, and center vortices morph into one another as geometric parameters vary, revealing that the analytic picture of flux collimation holds in pure Yang-Mills theory under specific shape conditions and that transitions between configurations can be discontinuous.

Proton's isovector PDF with updated analysis of large-momentum lattice data

By applying state-of-the-art theoretical tools and empirically mitigating lattice artifacts to reanalyze existing large-momentum lattice QCD datasets, this study demonstrates that the proton's isovector parton distribution function is consistent with experimental global fits within approximately one standard deviation, validating the predictive capability of the large-momentum expansion approach.

Multi-particle states investigation with tensor renormalization group method

This paper investigates multi-particle states in the (1+1)d Ising model by combining the tensor renormalization group method with transfer matrix spectroscopy and impurity tensor networks to identify quantum numbers, extract one- to three-particle energy levels, and validate two-particle scattering phase shifts and three-particle degeneracies against theoretical predictions.

Emergent Andreev Reflection from a Lattice Duality Defect

This paper demonstrates that a purely lattice duality defect in a Majorana representation of the transverse-field Ising chain induces an emergent Andreev-like boundary condition by implementing a chiral fermion-parity flip, thereby providing a microscopic realization of the Emery–Kivelson boundary, Maldacena–Ludwig monopole scattering, and an axial U(1)AU(1)_A-symmetric charge-flip interface.
