Totpological superconductivity in two dimensional materials

Topological superconductivity is an intriguing quantum phenomenon that may potentially host an elementary block of fault-tolerant quantum computing—the Majorana fermion. This phenomenon is a combination of two quantum effects: the topological insulating state and superconductivity. In topological insulators, the topological states, i.e., edge states in two-dimensional case, are metallic states, while the surfaces are insulating. As the superconductivity requires metallic states, many recent studies reported that the superconducting states may coexist within the edge states induced by proximity to the bulk. I will present how topological superconductivity can be iinduced in two-dimensional materials.
