Noninterferometric experiments have been successfully employed to constrain models of spontaneous wave function collapse, which predict a violation of the quantum superposition principle for large systems. These experiments are grounded on the fact that, according to these models, the dynamics is driven…
We show that any dynamics collapsing the wave function in space implies diffusion in momentum. This is relevant since it means that, in order to test the validity of thiesse models, and in general of the quantum superposition principle, one can perform experiments, known as “non-interferometric”, which look for this diffusion effect. The main advantage…

We study the effects of the electromagnetic vacuum on the motion of a nonrelativistic electron. First we derive the equation of motion for the expectation value of the electron's position operator. We show how this equation has the same form as the classical Abraham-Lorentz equation but,…

In this paper, we review and connect the three essential conditions needed by the collapse model to achieve a complete and exact formulation, namely the theoretical, the experimental, and the ontological ones. These features correspond to the three parts of the paper. In…
