Chiral topological superconductor and half-integer conductance plateau from~quantum anomalous hall plateau transition

We propose to realize a two-dimensional chiral topological superconducting (TSC) state from the quantum anomalous hall plateau transition in a magnetic topological insulator thin LM through the proximity E ECT to a conventional s-wave superconductor. This state has a full pairing gap in the bulk and a single chiral majorana mode at the edge. The optimal condition for realizing such chiral tsc is to have inequivalent superconducting pairing amplitudes on top and bottom surfaces~of the doped magnetic topological insulator. We further propose several transport experiments to~detect the chiral TSC. One unique signature is that the conductance will be quantized into a half-integer plateau at the coercive eld in this hybrid system. in particular, with the point contact~formed by a superconducting junction, the conductance oscillates between E2=2H AND E2=H with the~frequency determined by the voltage across the junction. we close by discussing the feasibility of~these experimental proposals.
