Tjark Sievers

I’m a Physics master student currently working on my master thesis, a joint project between Prof. Tim Wehling at Universität Hamburg and Prof. Annica Black-Schaffer at Uppsala University. My research interest is the theory of superconductivity in strongly correlated electron systems.
