The Schroedinger-Newton model as N->Infinity limit of a N color model

Abstract

The generalization to N colors of a recently proposed non unitary two color model for the gravitational interaction in non relativistic quantum mechanics is considered. The N->Infinity limit is proven to be equivalent to the Schroedinger-Newton model, which, though sharing localization properties with the N=2 model, cannot produce decoherence.

The statement about the finite character of the field theoretic version of the model is more transparent
