1. Model of a Wave Diode in a Nonlinear System
University essay from Linköpings universitet/Teoretisk Fysik; Linköpings universitet/Tekniska högskolanAbstract : In this diploma work, two versions of the discrete nonlinear Schrödinger (DNLS) equation are used to model a nonlinear layered photonic crystal system; the cubic DNLS (cDNLS) equation and the saturable DNLS (sDNLS) equation. They both have site-dependent coefficients to break mirror symmetry with respect to propagation direction, as well as to describe the linear and nonlinear properties of the system. READ MORE

2. Characterization of attractors in a model for boundary-driven nonlinear optical waveguide arrays with disorder, gain and damping
University essay from Teoretisk Fysik; Tekniska högskolanAbstract : The purpose of this thesis is to study the effects of gain and damping on a nonlinear waveguide array with a strong disorder that is driven in the first site, and try to find regimes which have stable stationary solutions. This has been done with a modified DNLS (Discrete nonlinear Schrödinger equation). READ MORE

3. Comparison of classical and quantum properties in an extended Bose-Hubbard model
University essay from Teoretisk FysikAbstract : In order to explore a quantum version of a discrete nonlinear Schrödinger equation (DNLS), we quantize one nonlinear Schrödinger model, which is used to study different physical systems, e.g. coupled Bose-Einstein condensates. We will focus on small systems, like Dimer and Trimer. READ MORE
