A dynamical theory of nucleation.
This work concerns a new formulation of the theory of nucleation based on fluctuating hydrodynamics. It combines a nonequilibrium description of nucleation with classical Density Functional Theory in a consistent manner. The (unpublished) figure below shows the density distribution at different stages of the nucleation process as determined by numerical integration of the dynamical equation derived from the theory. The left panel illustrates the beginning of nucleation as a long-wavelength, small amplitude density fluctuation. The central panel shows snapshots from the evolution of the profile from the early, almost flat, profiles (the same as the first panel but on a much larger scale) to the critical cluster with a radius of about 10 units. The third, rightmost, planel shows a zoom of the post-critical profile where the formation of a depletion zone as the cluster grows is clearly visible. Read more here .
