Topology meets time-reversal symmetry breaking in FeSeTe superconductor
M. Roppongi, Y. Cai, K. Ogawa +21
Time-reversal symmetry breaking (TRSB) in magnetic topological insulators induces a Dirac gap in the topological surface state (TSS), leading to exotic phenomena such as the quantu…

Lifting of gap nodes by disorder in ultranodal superconductor candidate FeSe1-xSx
T. Nagashima, K. Ishihara, K. Imamura +8
The observation of time-reversal symmetry breaking and large residual density of states in tetragonal FeSeS suggests a novel type of ultranodal superconducting state wi…
