Improved bounds on collapse models from rotational noise of the Laser Interferometer Space Antenna Pathfinder mission

Carlesso, Matteo; Vinante, Andrea; Altamura, Davide Giordano Ario

We study spontaneous wave-function collapse models, which modify the Schrödinger equation with nonlinear and stochastic terms offering a solution to the quantum measurement problem. We find that constraints on the phenomenological parameters of the continuous spontaneous localization (CSL) model can be tightened using the recent analysis of the La…
