1. Superfluidity and Supersolidity in Ultracold Atomic Gases Beyond Mean Field
Sammanfattning : This thesis investigates ultracold bosonic systems using an extended mean-field formalism with a focus on their superfluid and supersolid properties. The dissertation comprises five chapters and four articles, where the chapters provide some background to the research put forward in articles. LÄS MER
2. Interaction effects in the transport of particles in nanowire quantum dots
Sammanfattning : Interactions between physical bodies constantly affect their properties. This thesis presents a theoretical study on the effects of interaction in few-body nanowire quantum dots. LÄS MER
3. Quantum Few-Body Physics with the Configuration Interaction Approach: Method Development and Application to Physical Systems
Sammanfattning : This dissertation, based on six included papers, theoretically investigates properties of quantum few-particle systems. An overview of related experimental research - ultra-cold trapped dilute gases, and electrons in quantum dots - is given, followed by a description of some of the studied many-particle phenomena - Bose-Einstein condensation, quantized vortices, Wigner localization and the Tonks-Girardeau gas.

4. Spin ice and demagnetising theory
Sammanfattning : Frustration, or the inability to simultaneously minimise all local interactions is, a phenomenon occurring in a broad number of physical systems. We will in this thesis focus on a class of frustrated ferromagnetic materials called spin ices and how both numerical and experimental techniques can be used to understand their properties. LÄS MER
