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…
When identical particles cease to be indistinguishable: violation of statistics in quantum spacetime
Nicola Bortolotti, Catalina Curceanu, Antonino Marciano +1
Quantum gravity may modify the fundamental symmetries that govern identical particles. In particular, noncommutative spacetime frameworks predict deformations of Bose and Fermi sta…
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…
Machine Learning Optimization of BEGe Detector Event Selection in the VIP Experiment
Simone Manti, Jason Yip, Massimiliano Bazzi +19
The VIP collaboration operates a Broad Energy Germanium detector at the Gran Sasso National Laboratory to measure radiation in the few keV to 100 keV range, aiming to search for sp…
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…
