Research output: Chapter in Book/Report/Conference proceedingConference contribution


We propose the realization of topological edge states in two-dimensional non-Hermitian parity-time symmetric structure with C6 symmetry. Also, we study the bulk topological invariants that explain the topological phase of the non-Hermitian Hamiltonian.
