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…
Exact time-evolving resonant states for open double quantum-dot systems with spin degrees of freedom
Akinori Nishino, Naomichi Hatano
We study time-evolving resonant states in an open double quantum-dot system, taking into account spin degrees of freedom as well as both on-dot and interdot Coulomb interactions. W…
Markovianity and non-Markovianity of Particle Bath with Dirac Dispersion Relation
Takano Taira, Naomichi Hatano, Akinori Nishino
The dynamics of a two-level system coupled to a particle bath with the Dirac dispersion relation is studied. We analytically show that closing the Dirac gap results in a transition…
Exact time-evolving scattering states in open quantum-dot systems with an interaction: Discovery of time-evolving resonant states
Akinori Nishino, Naomichi Hatano
We study exact time-evolving many-electron states of an open double quantum-dot system with an interdot Coulomb interaction. A systematic construction of the time-evolving states f…
Universal electric current of interacting resonant-level models with asymmetric interactions: An extension of the Landauer formula
Akinori Nishino, Naomichi Hatano, Gonzalo Ordonez
We study the electron transport in open quantum-dot systems described by the interacting resonant-level models with Coulomb interactions. We consider the situation in which the qua…
Entanglement generation through an open quantum dot: an exact approach
Takashi Imamura, Akinori Nishino, Naomichi Hatano
We analytically study entanglement generation through an open quantum dot system described by the two-lead Anderson model. We exactly obtain the transition rate between the non-ent…
