Summary

A connection between field-theoretic descriptions of condensation and density-functional theories of nucleation is established. The time-independent differential equation for the density profile of a liquid droplet that mediates the transition from liquid to gas phase is derived based on a variational principle. The droplet profile depends crucially on an attractive interaction term. A physically motivated form for the one-dimensional droplet profile is postulated, the droplet translational eigenmode for an infinite system is identified, and its contribution to the nucleation-rate prefactor is evaluated.
