We present a phase-and spin-dependent manipulation of leakage of a Majorana mode into a double quantum dot.We study the density of states (DOS) to show the effect of phase change factor on the Majorana leakage into (out) of a double quantum dot.The DOS is derived from the Green's function of the quantum dot by the equation of motion method,and exhibits a formant structure when φ =0,2π and a resonance shape when φ =0.5π and 1.5π.Also,it changes more strongly under the spin-polarized coefficient than the non-polarized lead.Such a theoretical model can be modified to explore the spin-dependent effect in the hybrid Majorana quantum dot system.
