  2. 1. High-efficiency dissipative Kerr solitons in microresonators

    Author : Òskar Bjarki Helgason; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dissipative Kerr solitons; dissipative solitons; nonlinear optics; microresonators; microcombs; optical frequency combs;

    Abstract : The microresonator comb (microcomb) is a laser source that generates equally spaced coherent lines in the spectral domain. Having a chip-scale size and the potential of being low cost, it has attracted attention in multiple applications. READ MORE

  4. 2. From exotic superconductivity to QCD and back again searching things in common

    Author : Egor Babaev; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical physics; Chrial symmetry; Pseudogap; vortices; knots; solitons; Teoretisk fysik; Physics; Fysik;

    Abstract : This thesis is devoted largely to two new features which Particle Physics and Condensed Matter theory have in common. The first part of the thesis is a discussion of formation of phases precursory to the chiral phase transition in relativistic models with four-fermion interactions, considered as toy models for QCD.

  5. 3. 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

  6. 4. 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
