Nonlinear non-Hermitian higher-order topological laser

Topological lasers are investigated in nonlinear, non-Hermitian, and topological lattice systems based on a quench dynamics starting from one site. Explicitly, we consider the topological laser in the Su-Schrieffer-Heeger model with two topological edge states and the second-order topological laser...
