[17/08/18] Phase transitions and nucleation processes have attracted considerable attention from both experimental and theoretical communities for many years, starting from the seminal work by Gibbs on thermodynamics which ultimately led to the so-called classical nucleation theory (CNT), which described e.g. vapour-liquid transition and droplet formation. Unfortunately, CNT is known to be rather limited and it fails even close to equilibrium. Our paper published in the New Journal of Physics [link] challenges the current status quo on nucleation research by proposing a novel theoretical framework based on fluctuating hydrodynamics, treating from the outset nucleation as it is, i.e. a nonequilibrium phenomenon. Using elements from stochastic processes, we express the stochastic dynamics of cluster formation in terms of the “natural” order parameter of the system given by the arc-length of the (nonclassical) nucleation pathway. We derive exact expressions for the nucleation rate and cluster distribution, which are experimentally accessible properties. Our predictions for the nucleation rate deviate from CNT by several orders of magnitude and are in qualitative agreement with experiments.
