Coexistence of parallel and series current paths in parallel-coupled double quantum dots in nonlinear transport regime
Tsuyoshi Hatano, Toshihiro Kubo, Shinichi Amaha +2
We investigated the electron transport properties of parallel-coupled double quantum dot (DQD) devices under magnetic fields. When a low magnetic field was applied, electron tunnel…
Emergent Weyl fermion excitations in TaP explored by 181-Ta quadrupole resonance
H. Yasuoka, T. Kubo, Y. Kishimoto +8
The Ta quadrupole resonance (NQR) technique has been utilized to investigate the microscopic magnetic properties of the Weyl semi-metal TaP. We found three zero-field NQR s…
Spin-1 Quantum Walks
Daichi Morita, Toshihiro Kubo, Yasuhiro Tokura +1
We study the quantum walks of two interacting spin-1 bosons. We derive an exact solution for the time-dependent wave function that describes the two-particle dynamics governed by t…
Coulomb interaction-induced Aharonov-Bohm oscillations
Toshihiro Kubo, Yasuhiro Tokura
We study the Coulomb interaction-induced Aharonov-Bohm (AB) oscillations in the linear response transport through a remote quantum dot which has no tunnel coupling but has Coulomb…
Quantum adiabatic pumping by modulating tunnel phase in quantum dots
Masahiko Taguchi, Satoshi Nakajima, Toshihiro Kubo +1
In a mesoscopic system, under zero bias voltage, a finite charge is transferred by quantum adiabatic pumping by adiabatically and periodically changing two or more control paramete…
Interaction effect on adiabatic pump of charge and spin in quantum dot
Satoshi Nakajima, Masahiko Taguchi, Toshihiro Kubo +1
We investigate the pumped charge and spin at zero-bias by adiabatic modulation of two control parameters using the full counting statistics with quantum master equation approach. F…
