Emergent localized states at the interface of a twofold PT-symmetric lattice

Emergent localized states at the interface of a twofold PT-symmetric lattice

We consider the role of nontriviality resulting from a non-Hermitian Hamiltonian without band topology that conserves twofold PT symmetry assembled by interconnections between a PT-symmetric lattice and its time-reversal partner. Twofold PT symmetry in the lattice produces additional surface excepti...
