Quantum Hall effect of the surface states in topological insulator
Shun-Qing Shen
We study the quantum Hall effect in the surface states of topological insulator in the presence of a perpendicular magnetic field in the framework of edge states. Motion of Dirac f…
Conductance plateau in quantum spin transport through an interacting quantum dot
Yun-Juan Bao, Ning-Hua Tong, Qing-Feng Sun +1
Quantum spin transport is studied in an interacting quantum dot. It is found that a conductance "plateau" emerges in the non-linear charge conductance by a spin bias in the Kondo r…
Using spin bias to manipulate and measure quantum spin in quantum dots
Hai-Zhou Lu, Shun-Qing Shen
A double-quantum-dot coupled to electrodes with spin-dependent splitting of chemical potentials (spin bias) is investigated theoretically by means of the Green's functions formalis…
Spin polarized current in a junction of zigzag carbon nanotube
Zhan-Feng Jiang, Jian Li, Shun-Qing Shen +1
We investigated spin-resolved electronic transport through a junction composed of a nonmagnetic metal electrode and a zigzag carbon nanotube by means of self-consistent Green's fun…
Topological quantum phase transition and the Berry phase near the Fermi surface in hole-doped quantum wells
Bin Zhou, Chao-Xing Liu, Shun-Qing Shen
We propose a topological quantum phase transition for quantum states with different Berry phases in hole-doped III-V semiconductor quantum wells with bulk and structure inversion a…
Deduction of Pure Spin Current from Spin Linear and Circular Photogalvanic Effect in Semiconductor Quantum Wells
Bin Zhou, Shun-Qing Shen
We study the spin photogalvanic effect in two-dimensional electron system with structure inversion asymmetry by means of the solution of semiconductor optical Bloch equations. It i…
