 Non-interferometric experiments with cold atoms. The recent advances in trapping, cooling and manipulating ensembles of atoms paved the way for testing collapse models with cold atoms. Similarly to optomechanical systems, bounds on the collapse parameters are derived by quantifying the Brownian noise induced by the collapse process. The focus is on the energy increase or the position diffusion. To make an example, if the atomic cloud can freely evolve, the energy will grow linearly with time, while the position spread goes with the cubic power. Experimental bounds were obtained from both variables and analyzed in Laloe, Muillin, and Pearle 2014 and Bilardello et al. 2016 respectively.
