Odd-frequency superconductivity and Meissner effect in the doped topological insulator Bi${}_2$Se${}_3$

Johann Schmidt, Fariborz Parhizgar, Annica M. Black-Schaffer

Doped Bi${}_2$Se${}_3$ is proposed to be a nematic superconductor originating from unusual inter-orbital pairing. We classify all induced superconducting pair correlations in Bi${}_2$Se$…
