Localized states in the continuum in low-dimensional systems
Khee-Kyun Voo, C. S. Chu
It is shown in this paper that for open systems, states which are localized in space, discrete in energy, and embedded in the continuum of extended states, can be sustained by low-…
Spin cloud induced around an elastic scatterer by the intrinsic spin-Hall effect
A. G. Mal'shukov, C. S. Chu
Similar to the Landauer electric dipole created around an impurity by the electric current, a spin polarized cloud of electrons can be induced by the intrinsic spin-Hall effect nea…
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…
Coherent quantum transport in the presence of a finite-range transversely polarized time-dependent field
C. S. Tang, C. S. Chu
This work investigates the quantum transport in a narrow constriction acted upon by a finite-range transversely polarized time-dependent electric field. A generalized scattering-ma…
Differential conductance of a saddle-point constriction with a time-modulated gate-voltage
C. S. Tang, C. S. Chu
The effect of a time-modulated gate-voltage on the differential conductance of a saddle-point constriction is studied. The constriction is modeled by a symmetric saddle-point p…
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…
