Quadratic Spatial Soliton Interactions
Quadratic spatial soliton interactions were investigated in this Dissertation. The first part deals with characterizing the principal features of multi-soliton generation and soliton self-reflection. The second deals with two beam processes leading to soliton interactions and collisions. These …

Soliton interactions and bound states
… presented in this thesis is concerned with soliton interactions and bound states. We consider a on-topological soliton in (1 + 1) dimensions and topological models in (2 + 1) and (3 + 1) dimensions. In chapter 2 we consider Qballs, which are non-topological solitons, in (1 + 1) dimensions. …

Controlled optical soliton propagation using theoretical tunable dispersion fibers
… this thesis a solution is proposed: controlled soliton propagation. This solution requires the use of new technology in the form of tunable dispersion fibers that can be tuned quickly and continuously. Assuming such a fiber can be created, control is applied so as to produce Gaussian pulses that …

Semiclassical Methods in Field Theories: The Use of Soliton and Instanton
The first part of this thesis is to study how solitons interact among themselves in Sine-Gordon system. We translate the information encoded in various known soliton solutions such as scattering time delays and oscillation periods into that of the corresponding quantities in particle dynamics. We …
