Chiral Majorana edge modes in d-wave superconductor/antiferromagnet heterostructures

In this work, we study the heterostructure of a d-wave superconductor coupled to an antiferromagnet. We show that Majorana fermion edge states can be created in the system even in the absence of spin-orbit coupling, given that a supercurrent is induced in the superconductor. The Majorana edge states exist even the bulk is gapless and they propagates perpendicular to the direction of the supercurrent. The Majorana modes can be detected through tunneling and heat transport measurements.
