Theory of active soft matter

Overview

The group “Theory of active soft matter” is a 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 mainly 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. Furthermore, we study a wide range of topics from various fields based on the methods of statistical physics. (Details)

Youtube channel:
A Youtube channel of the working group is currently under construction (Link to YouTube).
It will publish short tutorial videos that include especially topics from theoretical physics, which are important but insufficiently covered by textbooks.
