Parity-time phase transition in photonic crystals with [Formula: see text] symmetry
We investigate the parity-time (PT) phase transition in photonic crystals with [Formula: see text] symmetry, with balanced gain and loss on dielectric rods in the triangular lattice. A two-level non-Hermitian model that incorporates the gain and loss in the tight-binding approximation was employed t...
