Nematic Bogoliubov Fermi surfaces from magnetic toroidal order in FeSe${}_{1-x}$S${}_x$

Hao Wu, Adil Amin, Yue Yu +1

Recently it has been argued that the superconducting state of FeSe${}_{1-x}$S${}_x$ exhibits Bogoliubov Fermi surfaces for $x>0.17$. These Bogoliubov Fermi surfaces appear together wit…
