Abstract: Abstract The existence and stability of nonlinear stationary states in nonlinear saturable coupler with balanced gain–loss (the parity-time symmetric distribution) are studied. Propagation and switching of beams at the different initial excitations are investigated. read more here.

Abstract: An approach based on modal analysis is developed to describe the state space of a nonlinear dynamical system using finite-dimensional linear systems. This strategy provides meta-reduced-order modeling (meta-ROM) consisting of the modes, which are the… read more here.
