Quantum theory and Gravity: which way?

18 Dec 2014, 13:45 → 19 Dec 2014, 17:45 Europe/Rome

Aula Conversi (Laboratori Nazionali di Frascati)

Alessandra Fantoni (LNF), Angelo Bassi (TS), Catalina Oana Curceanu (LNF), Kristian Piscicchia (LNF)

The aim of the workshop is to discuss recent achievements and future perspectives in quantum theory and gravity, both from theoretical and experimental points of view. Which way we have to follow to unify these theories? Which are the possible experimental tests? Is there a new theory beyond the actual quantum mechanics, as collapse models might envisage? All these items and many others will be debated within this workshop. About 30 persons are expected to participate, among which well-known experts in the field.

14:00 → 17:45 Session Part I

14:00 Welcome

14:15 Gravity-related spontaneous disentanglement: cause of Newton force?

I revisit the model of gravity-related spontaneous wave function collapse together with its lasting problems like the issue of mass density resolution and of overwhelming environmental decoherence. I argue heuristically that G-related spontaneous collapses may be responsible for a "lazy" emergence of Newton gravity at a time scale of 1ms.
