1. Fermions in two dimensions and exactly solvable models
Abstract : This Ph.D. thesis in mathematical physics concerns systems of interacting fermions with strong correlations. For these systems the physical properties can only be described in terms of the collective behavior of the fermions. READ MORE

2. Correlation Effects in Nanostructures
Abstract : In this Ph.D. thesis I present the background and providefurther details to the work presented in the appended papers. The background consists of brief overviews of Kondo physics, Luttinger liquid theory, and conformal field theory. READ MORE

3. Interactions on the edge of a quantum spin Hall insulator
Abstract : Effects from electron-electron interactions on the edge of a quantum spin Hall insulator are studied using bosonisation and renormalisation group methods. First, a quantum spin Hall device with a point contact connecting two of its edges is considered. READ MORE

5. Interacting fermions and non-equilibrium properties of one-dimensional many-body systems
Abstract : Recent experimental progress on ultracold atomic gases have opened up the possibility to simulate many-body systems out of equilibrium. We consider such a system described by the Luttinger model, which is a model of interacting fermions in one spatial dimension.It is well known that the Luttinger model is exactly solvable using bosonization.
