强自旋轨道耦合下的Pauli自旋封锁

Pauli Spin Blockade in the Presence of Strong Spin-Orbit Coupling

J. Danon, Yu. V. Nazarov

摘要:

我们研究了在泡利自旋阻塞机制下,强自旋轨道耦合下双量子点中的电子输运。自旋轨道耦合的效果被纳入一个修改的interdot隧道耦合。我们阐明了外部磁场的作用,在点的核领域,和自旋弛豫。我们发现定性协议与实验观察,我们提出了一种方法来扩大范围的磁场中可以观察到的封锁。

英文摘要:

We study electron transport in a double quantum dot in the Pauli spin blockade regime, in the presence of strong spin-orbit coupling. The effect of spin-orbit coupling is incorporated into a modified interdot tunnel coupling. We elucidate the role of the external magnetic field, the nuclear fields in the dots, and spin relaxation. We find qualitative agreement with experimental observations, and we propose a way to extend the range of magnetic fields in which blockade can be observed.
