Heterogeneous nucleation in the Ising model — •David Winter, Peter Virnau, and Kurt Binder — Institut für Physik, Johannes Gutenberg-Universität Mainz

Nucleation is typically enhanced by the presence of a wall because the free energy of a droplet in contact with a wall is reduced in comparison to the free energy of a droplet in the bulk. The difference between the homogeneous and the heterogeneous case can be described by Turnbull's formula which determines the free energy of a droplet as a function of the contact angle given by Young's equation. In this work, we test this simple model with Monte Carlo simulations of the 3d Ising model.
