Non-Hermitian -wave superfluid and effects of the inelastic three-body loss in a one-dimensional spin-polarized Fermi gas
Hiroyuki Tajima, Yuta Sekino, Daisuke Inotani +3
We theoretically investigate non-Hermitian -wave Fermi superfluidity in one-dimensional spin-polarized Fermi gases which is relevant to recent ultracold atomic experiments. Cons…
Dense with matrix product states
Tomoya Hayata, Yoshimasa Hidaka, Kentaro Nishimura
We study one-flavor and lattice QCD in () dimensions at zero temperature and finite density using matrix product states and the density matri…
Chiral fermion on quantum computers
Arata Yamamoto, Tomoya Hayata, Katsumasa Nakayama
Quantum computation often suffers from artificial symmetry breaking. We should strive to suppress the artifact both by theoretical and technological improvements. The theoretical f…
Dynamical chirality production in one dimension
Tomoya Hayata, Katsumasa Nakayama, Arata Yamamoto
We discuss the quantum computation of dynamical chirality production in lattice gauge theory. Although the chirality of a lattice fermion is complicated in general dimensions, it c…
Two-dimensional lattice with an imaginary magnetic field
Tomoki Ozawa, Tomoya Hayata
We introduce a two-dimensional non-Hermitian lattice model with an imaginary magnetic field and elucidate various unique features which are absent in Hermitian lattice models with…
deformed formulation of Hamiltonian SU(3) Yang-Mills theory
Tomoya Hayata, Yoshimasa Hidaka
We study Yang-Mills theory in dimensions based on networks of Wilson lines. With the help of the deformation, networks respect the (discretized) $\math…
Chiral fermion in the Hamiltonian lattice gauge theory
Tomoya Hayata, Katsumasa Nakayama, Arata Yamamoto
We discuss the chiral fermion in the Hamiltonian formalism of lattice gauge theory. Although the naive chiral charge operator does not commute with the Hamiltonian, the commutable…
String-net formulation of Hamiltonian lattice Yang-Mills theories and quantum many-body scars in a nonabelian gauge theory
Tomoya Hayata, Yoshimasa Hidaka
We study the Hamiltonian lattice Yang-Mills theory based on spin networks that provide a useful basis to represent the physical states satisfying the Gauss law constraints. We focu…
