16. Quantum Holonomy for Many-Body Systems and Quantum Computation
Sammanfattning : The research of this Ph. D. thesis is in the field of Quantum Computation and Quantum Information. A key problem in this field is the fragile nature of quantum states. LÄS MER
17. Abelian and non-abelian quantum Hall hierarchies
Sammanfattning : A core tenet of condensed matter physics has been that different phases of matter can be classified according to Landau's symmetry breaking paradigm. It has become clear, however, that phases of matter exist that are not distinguished by symmetry, but rather by topology. LÄS MER
18. Study of the phase diagram of Zn symmetric chains
Sammanfattning : 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. LÄS MER
19. Photonic Waveguide Modelling of Non-Hermitian Hamiltonians
Sammanfattning : The branch of condensed matter physics focusing on topological phases of matter has rapidly grown into a major part of the research field. A common feature of topological models is their robust edge and corner states, that are robust against perturbations of the Hamiltonian. This work studies such edge and corner states experimentally.

20. Strongly Correlated Moiré Materials
Sammanfattning : 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.
