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 …

Advances in quantum technologies are giving rise to a revolution in the way fundamental
physics questions are explored at the empirical level. At the same time, they are the seeds …

The Majorana Demonstrator neutrinoless double-beta decay experiment comprises a 44 kg
(30 kg enriched in Ge 76) array of p-type, point-contact germanium detectors. With its …

Quantum theory is incredibly successful, explaining the microscopic world with great
accuracy, from the behaviour of subatomic particles to chemical reactions to solid-state …

The continuous spontaneous localization (CSL) model predicts a tiny break of energy
conservation via a weak stochastic force acting on physical systems, which triggers the …

Despite the unquestionable empirical success of quantum theory, witnessed by the recent
uprising of quantum technologies, the debate on how to reconcile the theory with the …

Collapse models describe phenomenologically the quantum-to-classical transition by
adding suitable nonlinear and stochastic terms to the Schrödinger equation, thus (slightly) …

Collapse models represent one of the possible solutions to the measurement problem.
These models modify the Schrödinger dynamics with nonlinear and stochastic terms, which …

Inflation solves several cosmological problems at the classical and quantum level, with a
strong agreement between the theoretical predictions of well-motivated inflationary models …

The possibility that gravity plays a role in the collapse of the quantum wave function has
been considered in the literature, and it is of relevance not only because it would provide a …
