Existence and stability of multisite breathers in honeycomb and hexagonal lattices
V. Koukouloyannis, P. G. Kevrekidis, K. J. H. Law +2
We study the existence and stability of multisite discrete breathers in two prototypical non-square Klein-Gordon lattices, namely a honeycomb and a hexagonal one. In the honeycomb…

Higher-order effects and ultra-short solitons in left-handed metamaterials
N. L. Tsitsas, N. Rompotis, I. Kourakis +2
Starting from Maxwell's equations, we use the reductive perturbation method to derive a second-order and a third-order nonlinear Schroedinger equation, describing ultra-short solit…
