Nonlinear modes and symmetries in linearly-coupled pairs of PT-invariant dimers
K. Li, P. G. Kevrekidis, B. A. Malomed
The subject of the work are pairs of linearly coupled PT-symmetric dimers. Two different settings are introduced, namely, straight-coupled dimers, where each gain site is linearly…

Nonlinear PT-symmetric plaquettes
Kai Li, P. G. Kevrekidis, Boris A. Malomed +1
We introduce four basic two-dimensional (2D) plaquette configurations with onsite cubic nonlinearities, which may be used as building blocks for 2D PT -symmetric lattices. For each…

Transfer and scattering of wave packets by a nonlinear trap
Kai Li, P. G. Kevrekidis, Boris A. Malomed +1
In the framework of a one-dimensional model with a tightly localized self-attractive nonlinearity, we study the formation and transfer (dragging) of a trapped mode by "nonlinear tw…
