1. Shake-up studies of model systems for adsorbates : Department of Quantum Chemistry, Uppsala University
Sammanfattning : Shake-up studies of model systems for adsorbates are presented. The molecule CO adsorbed on transition metal surfaces belong to one of the most studied systems in surface science. The interest is motivated by fundamental questions about the adsorbate-substrate interaction as well as technical applications, such as catalysis. LÄS MER
2. Computational studies of core level XPS satellites in transition metal systems : Department of Quantum Chemistry, Uppsala University
Sammanfattning : Upon core ionization of a free molecule or a molecule adsorbed on a metal surface, higher binding energy satellites are observed, so called "shake-up" satellites, which can be viewed as valence excitations simultaneously to the creation of the core hole. In this thesis, theoretical studies of such core level XPS satellites in transition metal systems are presented, as well as cluster calculations of XES spectra, using the quantum mechanical INDO method.

3. First principles modeling of soft X-ray spectroscopy of complex systems
Sammanfattning : The electronic structures of complex systems have been studied by theoretical calculations of soft x-ray spectroscopies like x-ray photoelectron spectroscopy, near edge x-ray absorption fine structure, and x-ray emission spectroscopies. A new approach based on time dependent density functional theory has been developed for the calculation of shake-up satellites associated with photoelectron spectra. LÄS MER
4. Up close and personal: How relational dynamics in founding teams are shaped by the context of entrepreneurship
Sammanfattning : Despite increased interest in the phenomena of team-based entrepreneurship, we still don’t know why some teams are more effective than others in their entrepreneurial pursuits. In fact, scholars acknowledge that we have yet to get a firm grasp on what teams ‘are’ in this unique work context, not least because their emotional and relational dynamics remain understudied.

5. Multi-electron processes in atoms and molecules - Experimental investigations by coincidence spectroscopy
Sammanfattning : This thesis presents studies on multi-electron processes in atoms and molecules initiated by single-photon absorption. The experimental techniques used for these studies rely on synchrotron radiation offered at large scale user facilities, and a magnetic bottle spectrometer. LÄS MER
