DOI: 10.1007/jhep02(2024)193
Abstract: Assuming that Quantum Mechanics is universal and that it can be applied over all scales, then the Universe is allowed to be in a quantum superposition of states, where each of them can correspond to… read more here.

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: 10.1103/2yy5-tj85
Abstract: Spontaneous collapse models aim to solve the long-standing measurement problem in quantum mechanics by modifying the theory's dynamics to include objective wave function collapses. These collapses occur randomly in space, bridging the gap between quantum… 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.
