论文摘要
我们研究了一个旋转双重量子点(DQD),该点在伪源阀构型中耦合到铅。相互作用和干扰的相互作用在稳定性图中产生了由系统参数调节的丰富谐振。在存在铁磁铅和伪旋转各向异性的情况下,这些共振分裂,变成倾角并获得Fano形状,从而揭示了DQD上诱导的合成自旋轨道耦合。最小模型得出的一组速率方程可捕获这些功能。该模型可以准确匹配通用主方程框架中完整系统获得的数值结果,并在共同尼尔近似中计算。
We investigate a spin-full double quantum dot (DQD) coupled to the leads in a pseudospin valve configuration. The interplay of interaction and interference produces in the stability diagram a rich variety of resonances, modulated by the system parameters. In presence of ferromagnetic leads and pseudospin anisotropy, those resonances split, turn into dips and acquire a Fano shape thus revealing a synthetic spin-orbit coupling induced on the DQD. A set of rate equations derived for a minimal model captures those features. The model accurately matches the numerical results obtained for the full system in the framework of a generalized master equation and calculated within the cotunneling approximation.
