Clusters formation of patchy particles — •Reint Hieronimus and Andreas Heuer — Westfälische Wilhelms-Universität Münster, Institut für physikalische Chemie, Corrensstrasse 30, 48149 Münster, Germany

A system of patchy particles can aggregate in different ways to clusters. The aggregation behaviour is determined by the particle geometry and the type of patch interaction. In order to estimate the probability of finding clusters of different sizes we calculated their free energy. This was done by performing Monte-Carlo simulations in combination with thermodynamic integration. Our method is independent of the chosen potential and can be used for any particle geometry. As a verification, we compared the simulation results to analytic results for a one-dimensional system using the well-known model by Kern and Frenkel.
