We investigate the kinetics of phase separation and the
phase behaviour in thin films via large scale Monte Carlo
simulations of coarse grained (polymer)modells. Three topical
problems will be addressed:
(1) Comparing MC simulations and dynamic mean field theory
we shall elucidate the role of the single chain dynamics
on the phase separation process.
(2) We shall conduct MC simulations on a coarse grained model
of a compressible mixture of a short polymer and a supercritical
solvent, which are targeted to test classical nucleation theory.
(3) The Wang-Landau algorithm (PRL 86, 2050 (2001)) shall be
implemented efficiently on a parallel computer, and we explore
the phase behaviour of a binary blend in confined geometry.
