Quantum coherent control of linear and nonlinear thermoelectricity on graphene nanostructure heat engines
Yuga Kodama, Nobuhiko Taniguchi
We theoretically show how structural modifications and controlling quantum coherency can enhance linear and nonlinear thermoelectric performance in graphene nanostructure heat engi…
Quantum control of nonlinear thermoelectricity at the nanoscale
Nobuhiko Taniguchi
We theoretically study how one can control and enhance nonlinear thermoelectricity by regulating quantum coherence in nanostructures such as a quantum dot system or a single-molecu…
Quantum thermodynamics of nanoscale steady states far from equilibrium
Nobuhiko Taniguchi
We develop an exact quantum thermodynamic description for a noninteracting nanoscale steady state that couples strongly with multiple reservoirs. It is demonstrated that there exis…
Multi-terminal Anderson impurity model in nonequilibrium: Analytical perturbative treatment
Nobuhiko Taniguchi
We study the nonequilibrium spectral function of the single-impurity Anderson model connecting with multi-terminal leads. The full dependence on frequency and bias voltage of the n…
Spin Current Generation as a Nonequilibrium Kondo Effect in a Spin-orbit Mesoscopic Interferometer
Nobuhiko Taniguchi, Kenta Isozaki
We study nonequilibrium generation of spin-dependent transport through a single-level quantum dot embedded in a ring with the Rashba spin-orbit coupling. We consider nonmagnetic sy…
Universal conductance enhancement and reduction of the two-orbital Kondo effect
Haruka Oguchi, Nobuhiko Taniguchi
We investigate theoretically the linear and nonlinear conductance through a nanostructure with two-fold degenerate single levels, corresponding to the transport through nanostructu…
