Anomaly of conserved and nonconserved axial charges in Hamiltonian lattice gauge theory
Yoshimasa Hidaka, Arata Yamamoto
We investigate the axial anomaly in Hamiltonian lattice gauge theory. The definition of axial charge operators is ambiguous, especially between conserved and nonconserved axial cha…

Analyzing the Higgs-confinement transition with non-local operators on the lattice
Yusuke Shimada, Arata Yamamoto
We study non-local operators for analyzing the Higgs-confinement phase transition in lattice gauge theory. Since the nature of the Higgs-confinement phase transition is topological…

Quantum circuit for lattice gauge theory at nonzero baryon density
Yoshimasa Hidaka, Arata Yamamoto
lattice gauge theory is the simplest discrete gauge theory with three-quark bound states, i.e., baryons. Since it has a finite-dimensional Hilbert space, it can be u…
