Suspensions of colloidal particles are widely studied as prototypical systems displaying self-assembly. Here I demonstrate how induced dielectric effects, realized through coatings and controlled by external fields, result in unexpected and until now unexplored aggregation and phase behavior. These observations also reveal striking connections between colloidal self-assembly and collective dynamics, and between dynamic behavior and classical thermodynamics.
