1. Topological band theory and Majorana fermions : With focus on self-consistent lattice models
Sammanfattning : 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. LÄS MER
2. Majorana Representation in Quantum Optics : SU(2) Interferometry and Uncertainty Relations
Sammanfattning : 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. LÄS MER
3. The one-dimensional Kondo Lattice in the Majorana Fermion representation
Sammanfattning : 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. LÄS MER
4. Non-Linear Canonical Methods in Strongly Correlated Electron Systems
Sammanfattning : 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. LÄS MER
5. Quark and lepton interactions : studies of quantum chromo dynamics and Majorana neutrinos
Sammanfattning : .... LÄS MER
