Chiral topological superconductor from quantum anomalous Hall state
Jing Wang (王靖)Department of Physics, Fudan University Abstract
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 film through the proximity effect 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. Several transport experiments have been proposed to detect the chiral TSC. One unique signature is that the conductance will be quantized into a half-integer plateau at the coercive field in this hybrid system. Some of the theoretical predictions are already borne out in recent experiment.
