1. Higher Forms and Dimensional Hierarchy in Topological Condensed Matter
Master-uppsats, KTH/FysikSammanfattning : This report discusses higher differential forms with applications in the study of topological phenomena. The integer quantum Hall effect is first discussed, demonstrating a connection between models on a lattice and quantum field theories bridged by a topological invariant, namely the Chern number.

2. Val och implementering av en varvtalssensor i växellådan på ett elektrifierat bandvagn
Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronikSammanfattning : This project was carried out in cooperation with the company BAE Systems Hägglunds AB in Örnsköldsvik, which produces vehicles for military as well as civil use. There is an ongoing project at BAE researching bandwagons using electricity as their source of energy, codename SIRIUS, and this investigation is part of it. LÄS MER
3. From the quantum Hall effect to topological insulators : A theoretical overview of recent fundamental developments in condensed matter physics
Kandidat-uppsats, Teoretisk fysikSammanfattning : In this overview I describe the simplest models for the quantum Hall and quantum spin Hall effects, and give some general indications as to the description of topological insulators. As a background to the theoretical models I will first trace the development leading up to the description of topological insulators . LÄS MER
