Invariants of Sequential Circuits and Generalized Non-Abelian Statistics
Shintaro Sato, Yoshimasa Hidaka, Ryohei Kobayashi
Non-invertible symmetries in quantum many-body systems generally give rise to sequential unitary circuits that move symmetry defects. In this paper, we investigate invariants defin…
Dense with uniform matrix product states
Kohei Fujikura, Yoshimasa Hidaka
We study cold dense single-flavor gauge theory in dimensions in the thermodynamic limit using a gauge-invariant variational uniform matrix product state an…
Onset of thermalization of q-deformed SU(2) Yang-Mills theory on a trapped-ion quantum computer
Tomoya Hayata, Yoshimasa Hidaka, Yuta Kikuchi
Nonequilibrium dynamics of quantum many-body systems is one of the main targets of quantum simulations. This focus - together with rapid advances in quantum-computing hardware - ha…
Phases of the -deformed Yang-Mills theory at large
Tomoya Hayata, Yoshimasa Hidaka, Hiromasa Watanabe
We investigate the -dimensional -deformed Yang-Mills theory in the lattice Hamiltonian formalism, which is characterized by three parameters: the numbe…
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…
Phase transition on superfluid vortices in Higgs-Confinement crossover
Tomoya Hayata, Yoshimasa Hidaka, Dan Kondo
We propose a novel method to distinguish states of matter by identifying spontaneous symmetry breaking on extended objects, such as vortices, even in the absence of a bulk phase tr…
