With my group, I am located in the research group
Statistical Physics of Soft Matter and Complex Systems that is led by Prof. Tanja Schilling.

The group's activities are summarized in the SOphT video [MP4, 90.7 MB] [MP4, 21.9 MB].

Recent finding: Anomalous Underscreening in the Restricted Primitive Model!

In Molecular Dynamics simulations of the Restricted Primitive Model we find the experimentally measured long-ranged correlations, but at lower ionic concentration than expected. In our work, published in Phys. Rev. Lett. 130 [link], we show that these correlations originate from ions forming neutral clusters that do not contribute to electostatic screening on larger scales.

We started the measurements in the project Paramecium random swim, which is kindly supported by the University of Freiburg.

      Our research is supported by the German Research Foundation (DFG) by a project on Capacitive density functional theory for structure and screening in ionic fluids and electric double layers with applications in sustainability.
