The effectiveness of collapse in the Diósi-Penrose model in the Markovian and non-Markovian regimes

We will continue the discussion about a theoretical bound set on the phenomenological parameter of the Diósi-Penrose model through the requirement that the collapse is strong enough to guarantee that macroscopic systems are well-localized. We will also discuss, at the level of the wave function, the generalization of the Diósi-Penrose to a non-Markovian regime. Then, we will obtain an approximated evolution for the density operator, and implement the collapse requirement of the Markovian case.
