Abstract

Near-field interferometry with large dielectric nano-particles opens the way to test fundamental modification of standard quantum mechanics at an unprecedented level. We showcase the capabilities of such platform, in a state-of-the-art ground-based experimental set-up, to set new stringent bounds on the parameters space of collapse models and highlight the future perspective for this class of experiments.
