1. Absorbing boundary techniques for the time-dependent Schrödinger equation
Abstract : Chemical dissociation processes are important in quantum dynamics. Such processes can be investigated theoretically and numerically through the time-dependent Schrödinger equation, which gives a quantum mechanical description of molecular dynamics.This thesis discusses the numerical simulation of chemical reactions involving dissociation.

2. Finite Difference Methods for Time-Dependent Wave Propagation Problems
Abstract : Wave propagation models are essential in many fields of physics, such as acoustics, electromagnetics, and quantum mechanics. Mathematically, waves can be described by partial differential equations (PDEs). In most cases, exact solutions to wave-dominated PDEs are nearly impossible to derive. READ MORE

3. Propagation of singularities for pseudo-differential operators and generalized Schrödinger propagators
Abstract : In this thesis we discuss different types of regularity for distributions which appear in the theory of pseudo-differential operators and partial differential equations. Partial differential equations often appear in science and technology. READ MORE

4. Numerical Methods for Wave Propagation : Analysis and Applications in Quantum Dynamics
Abstract : We study numerical methods for time-dependent partial differential equations describing wave propagation, primarily applied to problems in quantum dynamics governed by the time-dependent Schrödinger equation (TDSE). We consider both methods for spatial approximation and for time stepping. READ MORE
