1. Topological band theory and Majorana fermions : With focus on self-consistent lattice models
Abstract : One of the most central concepts in condensed matter physics is the electronic band structure. Although band theory was established more than 80 years ago, recent developments have led to new insights that are formulated in the framework of topological band theory. READ MORE

2. Majorana Representation in Quantum Optics : SU(2) Interferometry and Uncertainty Relations
Abstract : The algebra of SU(2) is ubiquitous in physics, applicable both to the atomic spin states and the polarisation states of light. The method developed by Majorana and Schwinger to represent pure, symmetric spin-states of arbitrary value as a product of spin-1/2 states is a powerful tool that allows for a great conceptual and practical simplification.

3. The one-dimensional Kondo Lattice in the Majorana Fermion representation
Abstract : This thesis analyses the possibilities offered by the representation of quantum mechanical operators in terms of Majorana fermions. These objects can be imagined as algebraic constituents of the fermionic degrees of freedom, allowing for a different representation of many Hamiltonians. READ MORE

4. Non-Linear Canonical Methods in Strongly Correlated Electron Systems
Abstract : In this thesis some new ideas to perform the analysis of Strongly Correlated Electronic Systems (SCES) are developed. In particular the use of non-linear canonical transformations is considered thoroughly. READ MORE
