Spin-polarized transport through a hybrid Majorana quantum dot system coupled ferromagnetic leads

By applying the slave-boson mean-field approximation to the highly correlated quantum dots (QDs), we investigate the spin polarized transport properties through serial two QDs coupled with Majorana bound states (MBSs) sandwiched between two ferromagnetic (FM) leads. We demonstrate the linear conductance and transmission properties which is dependent on the QD-MBS coupling strength and the spin polarization strength. We further discuss the exact up-and down-spin transmission properties in the parallel and anti-parallel configurations. We suggest that such a theoretical model can be used to study the physical phenomenon related to the spin manipulation transport in the hybrid Majorana quantum-dot systems.
