Gate-controllable spin-battery
Wen Long, Qing-feng Sun, Hong Guo +1
We propose a gate-controllable spin-battery for spin current. The spin-battery consists of a lateral double quantum dot under a uniform magnetic field. A finite DC spin-current is…

Anomalous Kondo effect of indirectly coupled double quantum dots
Qing-feng Sun, Hong Guo, Yupeng Wang
We report theoretical investigations of indirectly coupled double quantum dots (QD) side connected to an one-dimensional quantum wire. Due to quantum interference controlled by the…

Spin-current induced electric field
Qing-feng Sun, Hong Guo, Jian Wang
We theoretically predict that a pure steady state spin-current without charge-current can induce an electric field. A formula for the induced electric field is derived and we inves…
