摘      要：We consider a single-level quantum dot(QD)and a topological superconducting wire hosting Majorana bound states at its *** the equation of motion method,we give the analytical Green’s function of the QD in the noninteracting and the infinite interacting *** study the effects of QD energy level and the spin polarization on the density of states(DOS)and linear conductance of the *** the noninteracting case,the DOS resonance shifts with the change of energy level and it shows bimodal structure at large spin polarization *** the infinite interacting case,the up-spin linear conductance first increases and then decreases with the increase of spin polarization strength,but the down-spin is ***,the DOS shows a splitting phenomenon in the large energy level with the increase of spin polarization *** provides an interesting way to explore the physical properties of such spin dependent effect in the hybrid Majorana QD systems.
