Non-Hermitian extensions of higher-order topological phases and their biorthogonal bulk-boundary correspondence
Elisabet Edvardsson, Flore K. Kunst, Emil J. Bergholtz
Non-Hermitian Hamiltonians, which describe a wide range of dissipative systems, and higher-order topological phases, which exhibit novel boundary states on corners and hinges, comp…

Biorthogonal Bulk-Boundary Correspondence in Non-Hermitian Systems
Flore K. Kunst, Elisabet Edvardsson, Jan Carl Budich +1
Non-Hermitian systems exhibit striking exceptions from the paradigmatic bulk-boundary correspondence, including the failure of bulk Bloch band invariants in predicting boundary sta…
