Topological Solitons in Three-Band Superconductors with Broken Time Reversal Symmetry

Julien Garaud, Johan Carlström, Egor S. Babaev

Abstract

We show that three-band superconductors with broken time reversal symmetry allow magnetic flux-carrying stable topological solitons. They can be induced by fluctuations or quenching the system through a phase transition. It can provide an experimental signature of the time reversal symmetry breakdown.
