A little about meIn 2012, I joined the Theory of Quantum Matter group, part of Komko, in the department of physics of Stockholm University (as professor since September 2024). My field of research is condensed matter theory, and I am interested in low dimensional and strongly interacting systems, in particular toplogical phases of matter. In certain toplogical phases, particles with 'fractionalized quantum numbers' are possible. My research concentrates on the properties of these particles, how one can experimentally detect them, and utilize their properties. Systems in which one can study phase transitions from `conventional' phases to topological phases are crucial to understand the stability of topological phases. Finally, I am interested in the mathematical aspects of the study of the above mentioned phases. 
Supervision
I am supervising PhD student Alexander Fagerlund.
Teaching
During the academic year 23/24, I will be teaching
 `Natural Science for Upper Secondary School Teachers  Physics', FK2010 (15 ects).
 `Foundation year in natural science  Physics 2' (6 ects).
In addition, I will coordinate the course Introduction to Conformal Field theory as a 'peer study course' during the fall of 2023.
I am responsible for the master program in theoretical physics, information in english; information på svenska.
