Topological defects in s$+$is and d$+$id superconductors

ORAL

Abstract

Recently arguments were advanced that various compounds can have s$+$is or d$+$id superconductivity. I will discuss topological defects which can arise in such superconducting states, their properties and experimental signatures. The allowed defects: vortices, domain walls and Skyrmions all have distinct magnetic features so their observation can be a confirmation of the s$+$is or d$+$id nature of superconducting states.
