Growth laws, pinning and localized structures: an experiment in sodium vapor

Abstract

The nucleation problem in systems with two equivalent or nearly equivalent phases has attracted a lot of attention in equilibrium and - more recently - non-equilibrium physics. In two or more spatial dimensions the dynamics of a nucleation bubble is governed by curvature effects and possibly a 'pressure force' if the two states are not exactly equivalent. In systems with non-conserved order parameters, the resulting coarsening dynamics was shown to follow a t1/2 power law [1]. So far, however, there has been no experimental demonstration of this fact in a nonlinear optical system.
