Abstract
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.
