Quantum transport on Bethe lattices with non-Hermitian sources and a drain
Naomichi Hatano, Hosho Katsura, Kohei Kawabata
We consider quantum transport in a tight-binding model on the Bethe lattice of finite generation, which we expect to be the first step toward analyzing electronic transport in a li…
Quantum walk with a local spin interaction
Manami Yamagishi, Naomichi Hatano, Kohei Kawabata +4
We introduce a model of quantum walkers interacting with a magnetic impurity localized at the origin. First, we study a model of a single quantum walker interacting with a localize…
Quantum Thermal Machines Improved by Internal Coupling: From Equilibrium to Non-equilibrium Limit Cycles
Jingyi Gao, Naomichi Hatano
We investigate how internal coupling influences the operation and performance of a quantum Otto cycle operating as the Gibbs-state limit cycle (GSLC), equilibrating limit cycle (EL…
Non-Hermitian Quantum Mechanics of Open Quantum Systems: Revisiting The One-Body Problem
Naomichi Hatano, Gonzalo Ordonez
We review analyses of open quantum systems. We show how non-Hermiticity arises in an open quantum system with an infinite environment, focusing on the one-body problem. One of the…
Proposal of a quantum version of active particles via a nonunitary quantum walk
Manami Yamagishi, Naomichi Hatano, Hideaki Obuse
The main aim of the present paper is to define an active particle in a quantum framework as a minimal model of quantum active matter and investigate the differences and similaritie…
