Event details

Dynamic Density Functional Theory (DDFT) is a statistical mechanics based approach used to model the dynamics of Brownian particles. It can be seen as a time-dependent extension of the static classical Density Functional Theory, or as the generalization of Fick's law to the diffusion of interacting particles. A typical DDFT is an integro-differential equation in terms of the equilibrium Helmholtz free energy functional.

In this theory club I'll outline the derivation of the most basic DDFT, in particular highlighting the various approximations made, and the associated advantages and disadvantages of the model.
