Improved noninterferometric test of collapse models using ultracold cantilevers

Friday, September 8, 2017

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.

ScienceNews announced the result: Minuscule jitters may hint at quantum collapse

General Galilei Covariant Gaussian Maps

Friday, September 8, 2017

A new paper by G. Gasbarri, M. Toros and A. Bassi has been published in Physical Review Letters. The authors analyze Galilean symmetries in non-Markovian Gaussian Completely positive maps.

They provide the specific mathematical structure that Completely Positive Gaussian Maps should have in order to satisfy Galilean symmetries.

Next they apply the results to discussing measures of macroscopicity based on classicalization maps, specifically addressing dissipation, Galilean covariance and non-Markovianity.
In the Letter they further propose a possible generalization of macroscopicity measure first defined by Nimmrichter and Hornberger.
