Welcome to the pages of the working group Wittkowski

Theory of active soft matter


The group “Theory of active soft matter” is a new working group at the Institute of Theoretical Physics of the University of Münster and supported through the Emmy Noether Programme of the German Research Foundation (Deutsche Forschungsgemeinschaft). Our research belongs to the field of soft condensed matter physics and has a focus on “active soft matter”. In particular, we investigate suspensions of passive and active colloidal particles. While ordinary passive colloidal particles are already widespread in everyday life and of great relevance, e. g., for chemical industry, active colloidal particles constitute a relatively new field of research, where the foundations for novel applications are currently being laid.

We are a relatively new working group and have begun our work at the University of Münster on the 1st October 2016.
