  2. 1. Nonlinear localization in discrete and continuum systems : applications for optical waveguide arrays

    Author : Michael Öster; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : An introcludion to the formation of coherent structures in spatially discrete and continuous systems is given. Of special interest is the phenomenon of nonlinear localization, where the self-focusing of an excitation is balanced by a dispersive process. READ MORE

  4. 2. Stability and Mobility of Localized and Extended Excitations in Nonlinear Schrödinger Models

    Author : Michael Öster; Magnus Johansson; Sergej Flach; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Non-linear dynamics; chaos; Icke-linjär dynamik; kaos;

    Abstract : This thesis is mainly concerned with the properties of some discrete nonlinear Schrödinger equations. These naturally arise in many different physical contexts as the limiting form of general dynamical lattice equations that incorporate nonlinearity and coupling. READ MORE
