Time-reversal symmetry breaking in Fe-based superconductors — •Andrey Chubukov — University of Minnesota, Minneapolis, MN USA

I will discuss different scenario for time-reversal symmetry breaking in the superconducting state of Fe-based high Tc superconductors. I will review earlier works on s+id and s+is states and discuss recent theoretical and experimental results suggesting possible realization of time-reversal symmetry breaking nematic superconducting state in FeSe.
