Improved noninterferometric test of collapse models using ultracold cantilevers

A new paper by A. Vinante, R. Mezzena, P. Falferi, M. Carlesso, and A. Bassi, to appear in Physical Review Letters, describes an improved experiment aiming at probing collapse models. The tiny oscillations of a very cold microcantilever have been accurately measured, leading to new stringent limits on the collapse parameters. Notably, the experiment shows evidence of a residual noise, in principle compatible with collapse models’ predictions.
