Spin Bias Measurement Based on a Quantum Point Contact
Yanxia Xing, Qing-feng Sun, Jian Wang
Electron charge transport through a quantum point contact (QPC) driven by an asymmetric spin bias is studied. A large charge current is induced when the transmission coefficient of…
Spin Nernst effect and Nernst effect in two-dimensional electron systems
Shu-guang Cheng, Yanxia Xing, Qing-feng Sun +1
We study the Nernst effect and the spin Nernst effect, that a longitudinal thermal gradient induces a transverse voltage and a spin current. A mesoscopic four-terminal cross-bar de…
Double quantum dot as detector of spin bias
Qing-feng Sun, Yanxia Xing, Shun-Qing Shen
It was proposed that a double quantum dot can be used to be a detector of spin bias. Electron transport through a double quantum dot is investigated theoretically when a pure spin…
Josephson current transport through a Quantum Dot in an Aharonov-Bohm Ring
Shu-guang Cheng, Yanxia Xing, X. C. Xie +1
The Josephson current through an Aharonov-Bohm (AB) interferometer, in which a quantum dot (QD) is situated on one arm and a magnetic flux threads through the ring, has been in…
Influence of dephasing process on the quantum Hall effect and the spin Hall effect
Yanxia Xing, Qing-feng Sun, Jian Wang
We study the influence of the phase relaxation process on Hall resistance and spin Hall current of a mesoscopic two-dimensional (2D) four-terminal Hall cross-bar with or without Ra…
