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…
