Kinetics of Phase Ordering in a Two-Component Fluid Membrane

We present a novel Monte Carlo simulation of the phase separation dynamics of a model fluid membrane. Such a phase segregation induces shape changes of the membrane and results in local `budding' under favourable conditions. We present a preliminary investigation of the nucleation regime and compute a variety of growth laws. Our study indicates that membranes with high viscosity, buckle on account of phase segregation. We discuss the relation between this dynamical buckling and the phenomenon of `capping' seen in biological membranes.
