Hamiltonian limit of (3+1)-dimensional SU(3) lattice gauge theory on anisotropic lattices [PDF]
Phys.Rev.D69:074509,2004, 2004 The extreme anisotropic limit of Euclidean SU(3) lattice gauge theory is examined to extract the Hamiltonian limit, using standard path integral Monte Carlo (PIMC) methods. We examine the mean plaquette and string tension and compare them to results obtained within the Hamiltonian framework of Kogut and Susskind.

SPECTRUM AND WAVE FUNCTIONS OF U(1)2+1 LATTICE GAUGE THEORY FROM MONTE CARLO HAMILTONIAN [PDF]
, 2011 We address an old problem in lattice gauge theory - the computation of the spectrum and wave functions of excited states. Our method is based on the Hamiltonian formulation of lattice gauge theory. As strategy, we propose to construct a stochastic basis of Bargmann link states, drawn from a physical probability density distribution.

Quantum sampling for the Euclidean path integral of lattice gauge theory [PDF]
Phys. Rev. D 105, 094501 (2022), 2022 Although the Hamiltonian formalism is so far favored for quantum computation of lattice gauge theory, the path integral formalism would never be useless. The advantages of the path integral formalism are the knowledge and experience accumulated by classical lattice simulation and manifest Lorentz invariance.

Cu–Au nanoparticles produced by the aggregation of gas‐phase metal atoms for CO oxidation
Aggregate, Volume 3, Issue 6, December 2022., 2022 The aggregation of gas‐phase Cu and Au atoms into Cu–Au nanoparticles with non‐equilibrium structures and compositions is studied using molecular dynamics. Density functional calculations reveal the significant effect of the structure of the obtained realistic models of Cu–Au nanoparticles on their CO and O binding properties as well as their CO ...
