Nonreciprocal wave propagation through open, discrete nonlinear Schroedinger dimers
Stefano Lepri, Giulio Casati
We consider asymmetric (nonreciprocal) wave transmission through a layered nonlinear, non mirror-symmetric system described by the one-dimensional Discrete Nonlinear Schrödinger eq…

Asymmetric Wave Propagation Through Nonlinear PT-symmetric Oligomers
J. D'Ambroise, P. G. Kevrekidis, S. Lepri
In the present paper, we consider nonlinear PT-symmetric dimers and trimers (more generally, oligomers) embedded within a linear Schr{ö}dinger lattice. We examine the stationary st…
