1. Molecular Hole Punching : Impulse Driven Reactions in Molecules and Molecular Clusters
Sammanfattning : When molecules are excited by photons or energetic particles, they will cool through the emission of photons, electrons, or by fragmenting. Such processes are often thermal as they occur after the excitation energy has been redistributed across all degrees-of-freedom in the system. LÄS MER
2. Molecular Electronics : A Theoretical Study of Electronic Structure of Bulk and Interfaces
Sammanfattning : This thesis deals with theoretical studies of the electronic structure of molecules used in the context of molecular electronics. Both studies with model Hamiltonians and first principle calculations have been performed. LÄS MER
3. Molecular Electronics : Insight from Ab-Initio Transport Simulations
Sammanfattning : This thesis presents the theoretical studies of electronic transport in molecular electronic devices. Such devices have been proposed and investigated as a promising new approach that complements conventional silicon-based electronics. LÄS MER
4. Solving the quantum scattering problem for systems of two and three charged particles
Sammanfattning : A rigorous formalism for solving the Coulomb scattering problem is presented in this thesis. The approach is based on splitting the interaction potential into a finite-range part and a long-range tail part. In this representation the scattering problem can be reformulated to one which is suitable for applying exterior complex scaling. LÄS MER
5. Reaction dynamics on highly excited states
Sammanfattning : In this thesis I have performed theoretical studies on the reaction dynamics in few-atom molecules. In particular, I have looked at reaction processes in which highly excited resonant states are involved. LÄS MER
