Role of mean free path in spatial phase correlation and nodal screening
Laboratoire de Physique et Modélisation des Milieux Condensés/CNRS Maison des Magistères/UJF, BP 166, 38042 Grenoble, France
Accepted: 25 April 2006
We study the spatial correlation function of the phase and its derivative, and related, fluctuations of topological charge, in two- and three-dimensional random media described by Gaussian statistics. We investigate their dependence on the scattering mean free path.
