Description
Random optical fields induce interactions between colloidal particles. Being the forces induced by the black body radiation the best known example. These fluctuation-induced interactions can be tuned by choosing an appropriate spectral energy density, hence it is possible to engineer the dynamics and equilibrium configurations. Using a coupled electric and magnetic dipoles model we present in this work how these optically induced pure pair interactions can be tuned and what are the limitations. As an application, we discuss the creation of stealth hyperuniform point patterns using such pair interactions. Moreover, we shall discuss the random fields-induced many body colloidal interactions and their properties.
