Topological semimetal phase in non-Hermitian Su–Schrieffer–Heeger model

Topological semimetal phase in non-Hermitian Su–Schrieffer–Heeger model

We explore the non-Hermitian Su–Schrieffer–Heeger model with long-range hopping and off-diagonal disorders. In the non-Hermitian clean limit, we find that the phase diagram holds topological semimetal phase with exceptional points except the normal insulator phase and the topological insulator phase...
