Gain-loss-driven travelling waves in PT-symmetric nonlinear metamaterials
M. Agaoglou, M. Feckan, M. Pospisil +2
In this work we investigate a one-dimensional parity-time (PT)-symmetric magnetic metamaterial consisting of split-ring dimers having gain or loss. Employing a Melnikov analysis we…
Dynamics of generalized PT-symmetric dimers with time periodic gain-loss
F. Battelli, J. Diblik, M. Feckan +3
A Parity-Time (PT)-symmetric system with periodically varying-in-time gain and loss modeled by two coupled Schrodinger equations (dimer) is studied. It is shown that the problem ca…
Traveling Waves of Discrete Nonlinear Schrodinger Equations with Nonlocal Interactions
Michal Feckan, Vassilis Rothos
Existence and bifurcation results are derived for quasi periodic traveling waves of discrete nonlinear Schrodinger equations with nonlocal interactions and with polynomial type pot…
Travelling Waves in Hamiltonian Systems on 2D Lattices with Nearest Neighbor Interactions
Michal Feckan, Vassilis M. Rothos
We study travelling waves on a two--dimensional lattice with linear and nonlinear coupling between nearest particles and a periodic nonlinear substrate potential. Such a discrete s…
