Dynamical scaling of matter density correlations in the Universe. An application of the dynamical renormalization group.
DOMINGUEZ A., HOCHBERG D., MARTIN-GARCIA J.M., PEREZ-MERCADER J. and SCHULMAN L.S.
Abstract (from CDS):
We show how the interplay of non-linear dynamics, self-gravity, and fluctuations leads to self-affine behavior of matter density correlations quite generically, i.e., with a power law exponent whose value does not depend in a very direct way on the specific details of the dynamics. This we do by means of the Renormalization Group, a powerful analytical tool for extracting asymptotic behavior of many-body systems.
