Pairing state at an interface of Sr${}_2$RuO${}_4$: parity-mixing, restored time-reversal symmetry, and topological superconductivity

Yasuhiro Tada, Norio Kawakami, Satoshi Fujimoto

We investigate pairing states realized at the (001) interface of a spin-triplet superconductor Sr${}_2$RuO${}_4$ on the basis of microscopic calculations. Because of a Rashba-type spin…
