Topological Interlayer Superconductivity in a van der Waals Heterostructure
Abstract
We show that when a hexagonal antiferromagnetic insulator (AFMI) is sandwiched between two transition metal dichalcogenide (TMD) monolayers in a commensurate way, magnons in the AFMI can mediate an interaction between electrons in the TMDs which gives rise to interlayer Cooper pairing. This opens coexisting extendend s-wave and chiral p-wave superconducting gaps, and the latter give rise to topological Majorana edge modes.
