Welcome to our group homepage!
Our group studies collective phenomena in quantum many-body systems that arise in
the presence of strong correlations. In our work we typically complement analytical
approaches by a variety of sophisticated numerical techniques that exploit concepts
from statistical physics, quantum information theory, and computer science.
We are embedded in a lively research environment at the Institute for Theoretical Physics in Cologne and part of a number of collaborative research and funding initiatives together with our experimental colleagues in the Physics Department.
