1. Resonant states in modulation-doped heterostructures
Abstract : This thesis deals with the properties of donors placed inside or outside a heterostructure quantum well (QW). The focus of the investigation has been on the formation of resonant states, which are a hybridization of the discrete localized impurity levels and the continuous two-dimensional QW subbands.

2. Turbulent and neoclassical transport in tokamak plasmas
Abstract : One of the greatest challenges of thermonuclear fusion is to understand, predict and to some extent control particle and energy transport in fusion plasmas. In the present thesis we consider theoretical and experimental aspects of collisional and turbulent transport in tokamak plasmas. READ MORE

3. Route attribution of chemical warfare agents : Retrospective classification of unknown threat samples
Abstract : Although chemical warfare agents (CWAs) are prohibited under international law, there have been numerous crimes that violates the 1997 Chemical Weapons Convention (CWC) during the last decade, especially in the civil war in Syria where sarin, mustard gas and chlorine have all been used. CWAs have also been used in political assassinations and attempts thereof. READ MORE

4. Temperature Gradient Instabilities and Transport in Toroidal Plasmas
Abstract : This thesis focuses on temperature gradient driven modes and their implications for heat and particle transport in toroidal plasmas. Some of the consequences of including an ion impurity species in a model for low frequency electrostatic modes and fluctuation driven transport are discussed. READ MORE

5. Diagnostics for advanced fusion plasma scenarios
Abstract : Over the past decade, fusion research has showed the potential of being a main candidate for energy production for future generations. Further advances in improved fusion performance are therefore vital. This thesis focuses on advanced fusion plasma scenarios and their diagnostic requirements. READ MORE
