Mean-field model for the density of states of jammed soft spheres
Mean-field model for the density of states of jammed soft spheres
We propose a class of mean-field models for the isostatic transition of systems of soft spheres, in which the contact network is modeled as a random graph and each contact is associated to $d$ degrees of freedom. We study such models in the hypostatic, isostatic, and hyperstatic regimes. The density …
