My expertise is theory of
electron transport in nanodevices driven into nonequilibrium by time-dependent field.
I addressed the following specific topics.
How to control and measure a single-electron
nonequilibrium excitations using the time-dependent field.
(belongs to study oaf single-electron
source and quantum tomography)
How the electric currents/noises are affected
by coherent interference of single/two-electron excitations.
(belongs
to study of electron-quantum optics and electron flying qubits)
What is the decoherence/relaxation mechanism
of the single-electron excitations.
I am interested in the general challenges:
How to understand the nonequilibrium quantum
dynamics of electrons.
How to use the understanding for quantum
information processing in nanodevices.
Related to this, I have background in quantum information theory: how to
quantify many-body quantum entanglement.
Recently, I am trying to address the topics:
How one can utilize the time-dependent external
field to enhance efficiencies in the nano-scale thermodynamic machines
(belongs to study of quantum thermodynamics)
Realization of quantum version of
voter model by using quantum feedback control.
(belongs to study of quantum
Maxwell demon)
