A post-Newtonian Gravitational Collapse Model from Linearized Gravity

Understand

We introduce a general gravity-related collapse mechanism based on linearized gravity.

• Starting from the weak-field limit of general relativity, gravitoelectromagnetism suggests an effective coupling between the gravitoelectric potential and the mass density distribution.
• At the same time, it provides a similar relation for the gravitomagnetic vector potential and the mass current.
• Following a hybrid (classical-quantum) dynamics approach, these couplings lead to a master equation whose non-unitary part is determined by the underlying mass distribution and currents.
