Tuning of coupling modes in laterally parallel double open quantum dots
Chi-Shung Tang, Wing Wa Yu, Vidar Gudmundsson
We consider electronic transport through laterally parallel double open quantum dots embedded in a quantum wire in a perpendicular magnetic field. The coupling modes of the dots ar…
A state with negative binding energy induced by coherent transport in a quantum wire
Vidar Gudmundsson, Chi-Shung Tang, Andrei Manolescu
In a two-dimensional quantum wire in a perpendicular magnetic field with a smooth embedded repulsive scattering potential we find in the multimode conductance resonances caused by…
Transport through a quantum ring, a dot and a barrier embedded in a nanowire in magnetic field
Vidar Gudmundsson, Yu-Yu Lin, Chi-Shung Tang +3
We investigate the transport through a quantum ring, a dot and a barrier embedded in a nanowire in a homogeneous perpendicular magnetic field. To be able to treat scattering potent…
Generation of spin current and polarization under dynamic gate control of spin-orbit interaction in low-dimensional semiconductor systems
C. S. Tang, A. G. Mal'shukov, K. A. Chao
Based on the Keldysh formalism, the Boltzmann kinetic equation and the drift diffusion equation have been derived for studying spin polarization flow and spin accumulation under ef…
Multi-mode transport through a quantum nanowire with two embedded dots
Vidar Gudmundsson, Gudny Gudmundsdottir, Jens Hjorleifur Bardarson +3
We investigate the conductance of a quantum wire with two embedded quantum dots using a T-matrix approach based on the Lippmann-Schwinger formalism. The quantum dots are represente…
Coherent electronic transport in a multimode quantum channel with Gaussian-type scatterers
Jens Hjorleifur Bardarson, Ingibjorg Magnusdottir, Gudny Gudmundsdottir +3
Coherent electron transport through a quantum channel in the presence of a general extended scattering potential is investigated using a T-matrix Lippmann-Schwinger approach. The f…
