Introducing a Kondo-type interaction to the model of quantum walkers
Manami Yamagishi, Naomichi Hatano, Kohei Kawabata +4
We introduce a model of discrete-time quantum walkers interacting with a lozalized magnetic impurity. Each quantum walker interacts with an impurity, through which multiple quantum…

Roles of the Internal Coupling: From Equilibrium to Non-Equilibrium Dynamics
Jingyi Gao, Naomichi Hatano
We identify the precise thermodynamic roles of internal coupling in quantum thermal machines by analyzing the quantum Otto cycle across thermalized Gibbs-state limit cycles (GSLC)…

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…
