Possible existence of a band of extended states induced by inter-Landau-band mixing in quantum Hall system
Gang Xiong, Shi-Dong Wang, Qian Niu +4
The mixing of states with {\it opposite chirality} in quantum Hall system is shown to have delocalization effect. It is possible that extended states may form bands because of this…
Bias-controllable intrinsic spin polarization in a quantum dot
Qing-feng Sun, X. C. Xie
We propose a novel scheme to efficiently polarize and manipulate the electron spin in a quantum dot. This scheme is based on the spin-orbit interaction and it possesses following a…
The definition of the spin current: The angular spin current and its physical consequences
Qing-feng Sun, X. C. Xie
We find that in order to completely describe the spin transport, apart from spin current (or linear spin current), one has to introduce the angular spin current. The two spin curre…
Quantum size effects on the perpendicular upper critical field in ultra-thin lead films
Xin-Yu Bao, Yan-Feng Zhang, Yupeng Wang +4
We report the thickness-dependent (in terms of atomic layers) oscillation behavior of the perpendicular upper critical field in the ultra-thin lead films at the reduc…
