In this report, we present a topological phase transition induced by on-site gain and loss in a photonic Chern insulator based on a non-Hermitian extension of Haldane model. By arranging the gyromagnetic rods in a honeycomb lattice, the gain and loss parameter is tuned to achieve a non-Hermiticity-i...
