Atomic correlation effects in collapse-induced spontaneous radiation
Simone Manti, Nicola Bortolotti, Lajos Diósi +2
Collapse models introduce stochastic and nonlinear modifications in the quantum dynamics, predicting observable effects, such as spontaneous radiation from charged particles, which…

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 Coll…

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…
