Particle-resolved Instabilities in Colloidal Dispersions
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,
we shall discuss lane and band formation in oppositely
driven colloidal mixtures,
both in DC and AC driving fields. The experimental realization in colloids
and dusty plasmas is highlighted.
