Author: F. Palmero, with J. Cuevas, R. Carretero-González, P.G. Kevrekidis and W. Królikowski (pdf file, 3 MB).

Abstract: We analyze the existence, stability, dynamical formation and mobility properties of localized solutions in systems described by the non-linear Schródinger equation with a linear point defect. We consider both attractive and repulsive defects in a focusing lattice.
