Highly Anisotropic Superconducting Gap in Nematically Ordered and Tetragonal Phases of FeSe${}_{1-x}$S${}_x$

Y. Sato, S. Kasahara, T. Taniguchi +5

FeSe has a unique ground state in which superconductivity coexists with a nematic order without long-range magnetic ordering at ambient pressure. Here, to study how the pairing int…
