Chair for Theoretical Solid State Physics
Prof. Dr. Jan von Delft
Strongly correlated quantum systems · Advanced numerical methods · Quantum matter
We study strongly interacting quantum many-body systems using advanced numerical and analytical methods. The chair hosts two research groups:
|
von Delft Group
Tensor networks, numerical renormalization group, functional RG, quantum criticality, Hund metals, strange metals.
