1. Effects of Spin-Orbit Interactions in Ferromagnetic Metal Nanoparticles
Sammanfattning : This thesis is a theoretical investigation of the effects of spin-orbit (SO) interactions in ferromagnetic metal nano-particles. Part I of the thesis is devoted to an elementary introduction of the research field, including recent experimental advances which partly motivated the work presented here. LÄS MER
2. A Play of Light and Spins: Excitation and Detection of Non-linear Magnetization Dynamics using Light
Sammanfattning : The excitation and detection of magnetization dynamics play key roles in the field of spintronics and magnonics. In this thesis, we investigate a contactless method of exciting nonlinear magnetization dynamics using a femtosecond pulsed laser, and study the same with a Brillouin Light Scattering (BLS) microscope.

3. Strongly Correlated Models in One Dimension from a Density Matrix Renormalization Group Perspective
Sammanfattning : The density matrix renormalization group (DMRG) is a numerical method for studying low dimensional strongly correlated models. The study of these models is one of the most active areas of condensed matter physics today and has been spurred not only by the discovery of high temperature superconductivity but also by experiments on new compounds.

4. Raman Scattering Studies of High-Tc Superconductors
Sammanfattning : This thesis describes Raman scattering investigations of cuprate high-Tc superconductors. The objective is to gain further knowledge on the physical properties that are relevant for the appearance of high-Tc superconductivity. LÄS MER
