Mathematical Quantum Physics

 

Pubquiz-Mar21
The group in March 2021, during an online pub quiz together with the Algebra group of the University of Innsbruck.

 

We are a recently established research group located at the Institute for Theoretical Physics of the University of Innsbruck, Austria. Group members are listed under People, and open positions in Open positions. Our research topics are explained in Research topics. Our publications are listed in Publications
