Collapse models: main properties and the state of art of the experimental tests
arXiv:1907.12460 · doi:10.1007/978-3-030-31146-9_1
Abstract
Collapse models represent one of the possible solutions to the measurement problem. These models modify the Schrödinger dynamics with non-linear and stochastic terms, which guarantee the localization in space of the wave function avoiding macroscopic superpositions, like that described in the Schrödinger's cat paradox. The Ghirardi-Rimini-Weber (GRW) and the Continuous Spontaneous Localization (CSL) models are the most studied among the collapse models. Here, we briefly summarize the main features of these models and the advances in their experimental investigation.
