6. Study of the phase diagram of Zn symmetric chains
Abstract : In this thesis we study the phase diagrams of Zn symmetric chains. We start with investigating the topological phases of the Kitaev chain, a Z2 symmetric model, with long range couplings and a phase gradient. READ MORE

7. Non-local behaviour from local interactions
Abstract : With the discovery of the quantum Hall effect more than thirty years ago, a whole new field emerged—that of topological quantum matter. This field is now a very mature one, and many different aspects are covered in the literature. READ MORE

8. Strongly Interacting Electrons in One and Two Dimensions
Abstract : In this thesis I present a theoretical study of three differentstrongly correlated systems: Luttinger liquids, spin-1 chains andthe two-dimensional spin-1/2 Heisenberg model.For every sub-field of our research I summarize the background andprovide further details to the work presented in the appendedpapers.

9. Antiferromagnets and Luttinger Liquids: Two Strongly Correlated Systems
Abstract : Strongly correlated systems show a variety of intriguing properties and have been extensively studied over the years. In this thesis two strongly correlated systems are discussed: the two-dimensional antiferromagnet and the Luttinger liquid. The Luttinger liquid has attracted much interest as a paradigm of non-Fermi liquid behavior. READ MORE

10. Some Aspects of Non-Perturbative Quantum Field Theory
Abstract : The aim of this thesis is to describe some different ways in which non-perturbative methods enter in quantum field theory. In the thesis such methods enter in 1+1-dimensional theories: various Yang-Mills theories and electrodynamics. It also enters when treating charged bosons or fermions interacting with an external, classical field. READ MORE
