Exceptional non-Hermitian topological edge mode and its application to active matter
Topological phenomena appear in non-Hermitian systems but the fundamental principles of the edge modes remain less understood. Here, Sone et al. report robust gapless edge modes due to topological structure around an exceptional point rather than bulk-edge correspondence.
