Spinodal Decomposition - Wikipedia - order parameter  ## Metadata - Author: **order parameter** - Full Title: Spinodal Decomposition - Wikipedia - Category: #articles - URL: https://en.m.wikipedia.org/wiki/Spinodal_decomposition#Fourier_transform ## Highlights - Spinodal decomposition is a mechanism by which a single thermodynamic phase spontaneously separates into two phases (without nucleation).[1] Decomposition occurs when there is no thermodynamic barrier to phase separation. As a result, phase separation via decomposition does not require the nucleation events resulting from thermodynamic fluctuations, which normally trigger phase separation
