D-dimensional elastic networks randomly embedded in a d > D dimensional euclidean space; are studied employing Hartree (Gaussian) approximation. In presence of an energy depending on the mean curvature this approach leads to the prediction of a phase transition between a flat and a crumpled regime as the bending rigidity decreases in agreement with previous approximate calculations.

Abstract
D-dimensional elastic networks randomly embedded in a d > D dimensional euclidean space; are studied employing Hartree (Gaussian) approximation. In presence of an energy depending on the mean curvature this approach leads to the prediction of a phase transition between a flat and a crumpled regime as the bending rigidity decreases in agreement with previous approximate calculations.File in questo prodotto:
