Abstract: A convergent approximation is proposed for a mean field density–density correlation function in a system with a two-phase interface. It is based on a fourth-order expansion of the Hamiltonian in terms of fluctuations around the equilibrium profile. The approach is illustrated by one- and three-dimensional calculations for systems characterized by the Ginzburg–Landau functional.
