Evidence for an edge supercurrent in the Weyl superconductor MoTe 2
Abstract
Many materials with topologically nontrivial band structures are characterized by currents that run around the edge of the sample and typically consist of single excitations. It is an open question whether a topological material that is also a superconductor can support an edge current that consists of paired excitations. W. Wang et al. studied the Weyl superconductor molybdenum ditelluride and, using systematic transport measurements in the presence of a magnetic field, revealed the signatures of an edge supercurrent.
