Topological states in non-Hermitian two-dimensional Su-Schrieffer-Heeger model

C. Yuce, H. Ramezani

A non-Hermitian topological insulator with real spectrum is interesting in the theory of non-Hermitian extension of topological systems. We find an experimentally realizable exampl…

Topological states at exceptional points

C. Yuce

We consider an N-level non-Hermitian Hamiltonian with an exceptional point of order N. We define adiabatic equivalence in such systems and explore topological phase. We show that t…

Spontaneous topological pumping in non-Hermitian systems

C. Yuce

We introduce modulational instability in non-Hermitian systems to study state conversion of topological edge states. We show that state conversion in non-Hermitian systems leads to…
