Calculating Coexistence in a two-field Phase-Field-Crystal model — •Max Philipp Holl¹ and Uwe Thiele^1,2 — ¹Institut für Theoretische Physik, Westfälische Wilhelms-Universität Münster, Wilhelm-Klemm-Straße 9, D-48149 Münster, Germany — ²Center for Nonlinear Science (CeNoS), Westfälische Wilhelms-Universität Münster, Corrensstr. 2, D-48149 Münster, Germany

We show that well-established numerical continuation methods can be employed to calculate the fully nonlinear phase behaviour in a range of thermodynamic systems. This method is illustrated by applying it to a two-field Phase-Field-Crystal model describing the crystallisation of a mixture of two types of colloidal particles. We compare the resulting phase diagrams containing different liquid and crystalline phases to those obtained from a one-mode approximation.
