Abstract
The collapse models were proposed more than 30 years ago to save the poor Schrödinger’s cat from its zombie-fate. In these models the standard Schrödinger equation is modified with the introduction of non-linear and stochastic terms, naturally collapsing the wave function in space. Ghirardi was pioneering these models, which predict deviations from the standard Quantum Mechanics. One of these predictions is the emission of a “spontaneous radiation”, which we explored to set the most stringent limits on the collapse models parameters in a broad range. This allowed us paraphrasing the title of his famous book, to sneak a look at Ghirardi’s cards.
