Christian Spånslätt Rugarn

Doctor at Applied Quantum Physics

I am a postdoc in the Applied Quantum Physics Group at MC2, working on strongly correlated electrons in nanoscale conductors. Presently, I investigate how electrical noise due to temperature gradients can be used to probe properties of these systems.

I obtained my PhD in 2018 at Stockholm University, supervised by Eddy Ardonne and Hans Hansson. Between 2018 and 2020, I worked as a postdoc in the group of Alexander Mirlin at Karlsruhe Institute of Technology in Germany. There, I studied transport on fractional quantum Hall edges. In 2021, I joined the group of Janine Splettstoesser.

Since 2022, I am a Marie Curie Sklodowska Individual Fellow with the project TEAPOT: Thermal Probes of Fractional Quantum Hall Transport. This research is financed by the EU Horizon 2020 programme.
