1. Order in Strongly Correlated Quasi-One-Dimensional Systems : Solving Higher-Dimensional Systems Combining Matrix-Product-State Methods and Mean-Field Theory
Abstract : Since their discovery the understanding of unconventional superconductors (USCs) has posed a great challenge in condensed matter physics. One central problem, both of theory and experiment, lies in determining the microscopic origin of electron pairing in such systems. READ MORE

2. Strongly Correlated Moiré Materials
Abstract : Recent advances in materials science have established Moiré materials as a new highly tunable and versatile form of quantum matter. When two dimensional atomic layers are brought into proximity, a tiny relative twist or a slight lattice mismatch produces Moiré patterns manifested in a superlattice structure with a lattice constant that is much larger than the lattice constants of the constituent layers.

3. Photoelectron spectroscopy on strongly correlated systems
Abstract : This work presents photoelectron spectroscopy data on somestrongly correlated systems. The electronic structure of the3dtransition metal oxides NiO and CoO have been studiedwith angle resolved and resonant photoemission. In the lattercase, both NiO and CoO show strong resonance effects at themetal absorption edges. READ MORE

4. 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

5. Theoretical methods for the electronic structure and magnetism of strongly correlated materials
Abstract : In this work we study the interesting physics of the rare earths, and the microscopic state after ultrafast magnetization dynamics in iron. Moreover, this work covers the development, examination and application of several methods used in solid state physics. The first and the last part are related to strongly correlated electrons.
