Perturbative Dynamics of Stationary States in Nonlinear Parity-Time Symmetric Coupler

Jyoti Prasad Deka, Amarendra K. Sarma

We investigate the nonlinear parity-time (PT) symmetric coupler from a dynamical perspective. As opposed to linear PT-coupler where the PT threshold dictates the evolutionary chara…
