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…
ac Josephson effect in the resonant tunneling through mesoscopic superconducting junctions
Yu Zhu, Qing-feng Sun, Wei Li +2
We investigate ac Josephson effect in the resonant tunneling through mesoscopic superconducting junctions. In the presence of microwave irradiation, we show that the trajectory of…
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…
Writing Spin in a Quantum Dot with Ferromagnetic and Superconducting Electrodes
Yu Zhu, Qing-feng Sun, Tsung-han Lin
We propose an efficient mechanism for the operation of writing spin in a quantum dot, which is an ideal candidate for qubit. The idea is based on the Andreev reflection induced spi…
