Ghirardi-Rimini-Weber model with massive flashes. (arXiv:1709.03809v1 [quant-ph])

We introduce a modification of the Ghirardi-Rimini-Weber (GRW) model in which
the flashes (or collapse space-time events) source a classical gravitational
field. The resulting semi-classical theory of Newtonian gravity preserves the
statistical interpretation of quantum states of matter in contrast with mean
field approaches. It can be seen as a discrete version of recent proposals of
consistent hybrid quantum classical theories. The model seems to be in
agreement with known experimental data and introduces new falsifiable
predictions: (1) particles do not attract themselves, (2) the $1/r$
gravitational potential of Newtonian gravity is cut-off at short ($\lesssim
10^{-7}$m) distances, and (3) gravity makes spatial superpositions decohere at
a rate inversely proportional to that coming from the vanilla GRW model.
Together, the last two predictions make the model experimentally falsifiable
for all values of its parameters.
