Phase diagrams of colloidal crystals

This is a visualization of the results of many simulations of a system of colloidal particles. The system is composed of two types of particles, large and small, where the small particles are grafted with varying numbers of linkers. The linkers which are attracted to the large particles, and otherwise, particles are mutually repulsive. The mixture's composition, or ratio of small to large particles, may also vary. Each simulation is initialized in a particular crystal structure and ends in its equilibrium particar crystal structure (which may be different from the initial structure).

On the left is a phase diagram mapping equilibrium crystal type as a function of temperature and number of linkers per small particle. On the right is a set of axes that hold pair correlation functions (g(r)) when those are plotted.
