- Electronic transport and correlation effects in topological materials, AP.R
Abstract
Electronic systems whose properties are influenced by symmetries and topological aspects of the band structure have been actively studied in the past few years. Examples include materials such as graphene, topological insulators and superconductors, and Weyl semi-metals. This research project proposes to investigate some fundamental theoretical questions which, in spite of the rapid adv...

- Magnetic noise due to Kondo impurities in spintronic devices, AP.R
Abstract
Conventional electronic devices based on charge currents are reaching their limit both in terms of miniaturization as well as energy dissipation. This realization has motivated research on spintronic devices that are based on the electron spin degree of freedom. Spintronic devices are more sensitive to environmental fluctuations, because, in addition to charge noise, they are also sensi...

- Wave-packet propagation in systems with spin-orbit interaction, BP.IC
Abstract
The goal of this project is to introduce the student to the practices andmethods used in research in theoretical condensed matter physics. Concretely,the student will work on analytical and numerical solutions for thetime-evolution of low-dimensional electron system systems with Rashbaspin-orbit interaction. Starting with the study of elementary Quantum Mechanicsconcepts, the student wi...
