Single-point position and transition defects in continuous time quantum walks
Zhi-Jian Li, J. B. Wang
We present a detailed analysis of continuous time quantum walks (CTQW) with both position and transition defects defined at a single point in the line. Analytical solutions of both…
Spin-dependent thermoelectric transport through double quantum dots
Qiang Wang, Haiqing Xie, Hujun Jiao +2
We study thermoelectric transport through double quantum dots system with spin-dependent interdot coupling and ferromagnetic electrodes by means of the non-equilibrium Green functi…
Controllable quantum spin precession by Aharonov-Casher phase in conducting ring
Shun-Qing Shen, Zhi-Jian Li, Zhongshui Ma
We investigate quantum spin transport in a structure of conducting ring, embedded in textured electric field, with two leads, and obtain an exact solution for the problem. The spin…
Aharonov-Casher phase and persistent current in a polyacetylene ring
Zhijian Li, J. Q. Liang, F. -C. Pu
We investigate a polyacetylene ring in an axially symmetric, static electric field with a modified SSH Hamiltonian of a polyacetylene chain. An effective gauge potential of the sin…
Larmor precession and tunneling time of a relativistic neutral spinning particle through an arbitrary potential barrier
Zhi-Jian Li, Jiu-Qing. Liang, D. H. Kobe
The Larmor precession of a relativistic neutral spin-1/2 particle in a uniform constant magnetic field confined to the region of a one-dimensional arbitrary potential barrier is in…
Larmor precession and barrier tunneling time of a neutral spinning particle
Zhi-Jian Li, J. Q. Liang, D. H. Kobe
The Larmor precession of a neutral spinning particle in a magnetic field confined to the region of a one dimensional-rectangular barrier is investigated for both a nonrelativistic…
