Texte intégralThe work presented in this thesis belongs to the field of numerical analysis, and builds on tools stemming from the study of partial differential equations (PDEs). We focus on time discretizations to nonlinear dispersive equations. The aim is to reduce the smoothness assumptions on the design and analysis of numerical methods, in order to treat low-regularity dynamics.Part I of the thesis develops novel low-regularity schemes, suited for general bounded domains. Chapter 2 presents first and second order convergence results for the Gross-Pitaevskii equation, when both the initial data and the potential are non-smooth. Chapter 3 generalizes the construction of these schemes to higher order and to a general class of nonlinear evolution equations with potentials.Part II of the thesis consists of Chapter 4, which considers higher-order constructions for randomized initial conditions. Part III of the thesis considers the long-time properties and invariants of the equation, and deals with structure-preserving schemes. We first introduce in Chapter 5 a novel symmetric time integrator for the nonlinear Schr ̈odinger equation. We give fractional convergence rates as a function of the Sobolev regularity of the initial data. Chapter 6 extends the latter work by constructing higher order symmetric integrators for a general class of dispersive equations. All these new symmetric schemes exhibit excellent structure preservation and convergence properties, which are witnessed in numerical experiments.The higher order extensions of Chapters 3, 4, 6 follow new techniques based on decorated tree series, inspired by singular stochastic PDEs via the theory of Regularity Structures

Rogue wave has been captivating to researchers. People have not fully understood rogue wave yet. The first strong scientific evidence was presented in 1995, just nearly a quarter-century ago. Since then, people gradually noticed that this phenomenon could occur in other media as well. The first optical rogue wave was reported in 2007. In the first part of this thesis, we try to understand this special phenomenon. The definition of rogue wave is introduced and then the physical mechanisms of rogue wave are given according to linear mechanism and nonlinear mechanism. From the nonlinear mechanism, nonlinear Schrödinger equation (NLS) can be obtained analytically. We would like to know more about rogue wave by investigating NLS equation. Similarly, the coupled NLS equations are obtained by considering the linear and nonlinear response in the birefringent optical fibers. The coupled NLS equations can describe the pulse propagation in those fibers. In the second part of this thesis, we review a numerical method that can solve NLS equation for which the equation is separated into linear and nonlinear part. The latter can be solved iteratively. The method has been modified in order to solve coupled NLS equations. In the third part of this thesis, we first consider examples that admit exact solutions in order to know the proposed algorithms work well in both NLS and coupled NLS cases. We then move to solve semi-classical NLS equation by using this method. Last but not least, we simulate rogue wave and two quantized vortex lattices in a rotating trapped Bose-Einstein condensate (BEC). We hope to know more about these phenomena through simulations.
