A class of nonunitary models of Newtonian gravity and its unicity

Sergio De Filippo, Filippo Maimone

A class of non-Markoffian nonunitary models for Newtonian gravity is characterized as following from some rather natural hypotheses. One of such models was previously obtained as t…

Nonunitary Newtonian Gravity

Filippo Maimone, Sergio De Filippo

It is shown that the Newtonian limit of a stable realization of HD gravity leads to a sharp transition, around 10^{11} proton masses, from the wavelike properties of microscopic pa…

Nonunitary Classically Stable HD Gravity

Sergio De Filippo, Filippo Maimone

Classical instability in fourth order gravity is cured at the expense of unitarity. The appearance of hidden degrees of freedom replicating those of ordinary matter allows for ordi…

Non-unitary HD gravity classically equivalent to Einstein gravity

Sergio De Filippo

Runaway solutions can be avoided in fourth order gravity by a doubling of the matter operator algebra with a symmetry constraint with respect to the exchange of observable and hidd…

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

Sergio De Filippo

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->Infi…

Gravity-induced entropy in the quantum motion of a macroscopic body

Sergio De Filippo

It is shown that a recently proposed model for the gravitational interaction in non relativistic quantum mechanics may turn to be relevant to the derivation of the second law of th…
