Dispersions of colloidal particles are excellent model systems of classical statistical mechanics in order to understand the principles of self-organization processes. Using an external field (e.g. electric or magnetic field) the effective interaction between the colloidal particles can be tailored and the system can be brought into non-equilibrium in a controlled way. In this talk, liquid crystalline colloidal dispersions will be discussed including: i) rhythmic clustering in driven nematics, ii) active liquid crystals in confinement, iii) nonequilibrium dynamics of colloidal nematics induced by in-plane rotating aligning fields.
