Dynamic density functional theory: correlated Brownian motion in colloidal systems — •Joachim Dzubiella — Physics Department, Technical University Munich, Germany

Classical density functional theory (DFT) has been proven to be a powerful mathematical tool to describe the equilibrium structure and phase behavior of correlated many-body systems (e.g., dense colloidal or biological fluids) in bulk or under the action of external potentials. Using the equilibrium functional a dynamic DFT can be constructed which accurately reproduces and predicts the strongly inhomogeneous steady-state or even time-dependent structure of systems in non-equilibrium. Here we present selected examples of colloidal systems out of equilibrium, such as driven polymer solutions, diffusion-controlled reactions, and sedimenting colloids in confinement.
