1. Zero-energy states in supersymmetric matrix models
Sammanfattning : The work of this Ph.D. LÄS MER
2. Transport properties of Bi2Se3 Topological Insulator Nanoribbon-Superconductor hybrid junctions
Sammanfattning : In recent years, topological superconductivity and Majorana zero-energy modes have attracted vast interest due to their potential for topologically protected quantum information processing. Hybrid devices involving a conventional s-wave superconductor (S) in proximity to a 3D Topological Insulator (TI) are expected to provide a platform for emulating and studying these phenomena.

3. Theoretical and Numerical Studies of Efimov States
Sammanfattning : In contrast to the classical case, the quantum three-body problem is amenable to qualitative analysis and, in some cases, even to analytic solutions. In 1970, Vitaly Efimov predicted that resonant two-body forces could give rise to a series of bound energy levels in three-particle systems. LÄS MER
4. Studies of Topological Superconductors via Defects
Sammanfattning : Defects from impurities, edges, junctions or domain walls have local detrimental effects on the superconducting state. Defects are also important in topological superconductors, and useful in studying the properties of the superconducting order parameter. LÄS MER
5. Edge Modes of Zn Symmetric Chains
Sammanfattning : In this Licentiate Thesis we will study the topological phases of Z2 and Z3 symmetric chains. We will present the Kitaev chain, a Z2 symmetric model of spinless fermions, and obtain all the eigenstates of the model with an open boundary condition which hosts Majorana zero modes in the topological phase.
