Nonequilibrium steady state in Lindblad dynamics for infinite quantum spin systems
Kenji Shimomura, Nagisa Hara, Seiichiro Kusuoka
We consider Lindblad dynamics of quantum spin systems on infinite lattices and define a nonequilibrium steady state (NESS) and a time-averaged nonequilibrium steady state (TANESS)…

Interacting Kitaev Chain with Supersymmetry
Urei Miura, Kenji Shimomura, Keisuke Totsuka
Lattice models with supersymmetry are known to exhibit a variety of remarkable properties that do not exist in the relativistic models. In this paper, we introduce an interacting g…
