1. Symmetry-protected topological phases: From Floquet theory to machine learning
Sammanfattning : It is by now a well known fact that boundary states in conventional time-independent topological insulators are protected against perturbations that preserve relevant symmetries. In the first part of this thesis, accompanying Papers A - C, we study how this robustness extends to time-periodic (Floquet) topological insulators. LÄS MER
2. Quantum theory of time-dependent transport in graphene
Sammanfattning : High-quality ballistic electronic devices made from graphene are becoming an experimental reality. Carbon-based electronics is heralded if not to succeed or surpass then to complement the existing semiconducting technology. LÄS MER
3. Diagrammatic many-body theory for atoms in high-intensity laser fields
Sammanfattning : .... LÄS MER
4. Charge and Energy Noise from On-demand Electron Sources
Sammanfattning : On-demand single electron sources (SES) are of key importance for future electronic applications such as metrology or quantum optics with electron. They allow for achieving a controlled, low-fluctuations flow of particles in a coherent mesoscopic conductor. LÄS MER
5. Stability of statically and periodically loaded structures
Sammanfattning : In this thesis different kinds of stability phenomena are analysed. Firstly the quasi-static behaviour of an elastic structure is studied for increasing loading. LÄS MER
