Generation of dc spin current in a narrow channel with Rashba and Dresselhaus spin-orbit interaction
Chi-Shung Tang, Yia-Chung Chang
We consider a finite range ac-biased front gate acting upon a quantum channel with Rashba and Dresselhaus spin-orbit interaction effects. The ac-biased gate, giving rise to a dynam…
Coherent magnetotransport spectroscopy in an edge-blocked double quantum wire with window and resonator coupling
Chi-Shung Tang, Vidar Gudmundsson
We propose an electronic double quantum wire system that contains a pair of edge blocking potential and a coupling element in the middle barrier between two ballistic quantum wires…
Magnetotransport in a double quantum wire: Modeling using a scattering formalism built on the Lippmann-Schwinger equation
Vidar Gudmundsson, Chi-Shung Tang
We model electronic transport through a double quantum wire in an external homogeneous perpendicular magnetic field using a scattering formalism built on the Lippmann-Schwinger equ…
Nonadiabatic quantum pumping in mesoscopic nanostructures
C. S. Tang, C. S. Chu
We consider a nonadiabatic quantum pumping phenomena in a ballistic narrow constriction. The pumping is induced by a potential that has both spatial and temporal periodicity charac…
Effects of a transversely polarized electric field on the quantum transport in narrow channels
C. S. Chu, C. S. Tang
The quantum transport in a narrow channel (NC) is studied in the presence of a time-dependent delta-profile electric field. The electric field is taken to be transversely polarized…
Connecting wave functions at a three-leg junction of one-dimensional channels
Khee-Kyun Voo, Shu-Chuan Chen, Chi-Shung Tang +1
We propose a scheme to connect the wave functions on different one-dimensional branches of a three-leg junction (Y-junction). Our scheme differs from that due to Griffith [Trans. F…
