Observation of unconventional band topology in a superconducting doped topological insulator, Cux-Bi2Se3: Topological Superconductor or non-Abelian superconductor?

L. Wray, S. Xu, J. Xiong +7

The Cu-doped topological insulator Bi${}_2$Se${}_3$ has recently been found to undergo a superconducting transition upon cooling, raising the possibilities that it is the first known "…
