DOI: 10.1038/s41567-021-01489-5
Abstract: The superposition principle is the cornerstone of quantum mechanics, leading to a variety of genuinely quantum effects. Whether the principle applies also to macroscopic systems or, instead, there is a progressive breakdown when moving to… read more here.

DOI: 10.1103/physreva.103.022214
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… read more here.

DOI: 10.1103/physrevlett.119.110401
Abstract: Spontaneous collapse models predict that a weak force noise acts on any mechanical system, as a consequence of the collapse of the wave function. Significant upper limits on the collapse rate have been recently inferred… read more here.

DOI: 10.3390/e25030500
Abstract: We make use of the powerful formalism of quantum parameter estimation to assess the characteristic rates of a continuous spontaneous localization (CSL) model affecting the motion of a massive mechanical system. We show that a… read more here.

Collapse Models: A Theoretical, Experimental and Philosophical Review
Sign Up to like & getrecommendations! Published in 2023 at "Entropy"
DOI: 10.3390/e25040645
Abstract: In this paper, we review and connect the three essential conditions needed by the collapse model to achieve a complete and exact formulation, namely the theoretical, the experimental, and the ontological ones. These features correspond… read more here.
