摘要

从理论上讨论了由电荷发射器和两条漏极线组成的三端装置中纠缠电子波的相干电荷和自旋输运,其中一条漏极线插入超导,另一条漏极线插入完美的吸收器或自旋滤波器。研究表明,利用超导体近间隙能量范围内的高度非线性色散关系,可以实现器件内电荷和自旋电流的自我控制。

Quantum Interference and Entanglement Effects in Hybrid Three-Terminal Splitters
Coherent charge and spin transport of entangled electron waves across a three-terminal setup formed by a charge emitter and two drain wires with a superconducting inset in one of them and a perfect absorber or a spin filter in the other is theoretically discussed. We show that self-controlled charge and spin currents across the device can be realized by employing highly nonlinear dispersion relation in the near-gap energy range of a superconductor.
