Abstract: Majorana fermions, as electronic quasi-particle modes in solid states, have been under the focus of research due to their exotic physical properties. While the evidence of Majorana fermions as zero-dimensional bound states has been well… read more here.

Abstract: Two-dimensional chiral topological superconductors can be realized in clean quantum anomalous Hall insulators under $s$-wave superconducting proximity, as is predicted by band theory. Under disorder, random domain walls hosting chiral Majorana fermion arise in space,… read more here.

Abstract: We predict conductance oscillations in a quantum-anomalous Hall 2d strip having a superconducting region of length $L_x$ with a chiral Majorana mode. These oscillations require a finite transverse extension of the strip $L_y$ of a… read more here.
