Nonlinear PT−symmetric plaquettes


Nonlinear PT−symmetric plaquettes

Guenther, U.; Kevrekidis, P.; Li, K.; Malomed, B.

Nonlinear coupled gain-loss oscillator oligomers (plaquettes) of 4-node and 5-node type in a 2D-plane are studied. Their specific PT-symmetry properties are investigated, the occurrence of exceptional points (up to third-order) as well as their various nonlinear dynamical regimes.
