2. Studies of Material Properties using Ab Initio and Classical Molecular Dynamics
Abstract : In this thesis, material properties have been examined under extreme conditions in computer-based calculations.The research on iron (Fe), nickel (Ni), and ferropericlase (Mg1-xFexO) are not only important for our understanding of the Earth, but also for an improved knowledge of these materials per se.

3. Combined Molecular Dynamics and Embedded-Cluster Calculations in Metal Oxide Surface Chemistry
Abstract : The development and improvement of the functionality of metal oxides in heterogeneous catalysis and other surface chemical processes can greatly benefit from an atomic-level understanding of the surface chemistry. Atomistic calculations such as quantum mechanical (QM) calculations and molecular dynamics (MD) simulations can provide highly detailed information about the atomic and electronic structure, and constitute valuable complements to experimental surface science techniques.

5. Numerical Methods for Molecular Dynamics with Nearly Crossing Potential Surfaces
Abstract : This thesis consists of four papers that concern error estimates for the Born-Oppenheimer molecular dynamics, and adaptive algorithms for the Car-Parrinello and Ehrenfest molecular dynamics.In Paper I, we study error estimates for the Born-Oppenheimer molecular dynamics with nearly crossing potential surfaces.
