Experimental exclusion of a generalized Károlyházy gravity-induced decoherence model
Nicola Bortolotti, Kristian Piscicchia, Matthias Laubenstein +4
We report new experimental constraints on the generalized version of the gravity-induced decoherence model originally proposed by Károlyházy. Using data collected by the VIP Collab…

Fundamental Limits on Clock Precision from Spacetime Uncertainty in Quantum Collapse Models
Nicola Bortolotti, Catalina Curceanu, Lajos Diósi +2
Models of spontaneous wavefunction collapse explain the quantum-to-classical transition without invoking the von Neumann measurement postulate. Prominent frameworks, such as the Di…
