Experimental Particle and Astro-Particle Physics Seminar

Monday 29 Mar 2021, 14:00 → 16:00 Europe/Zurich

Laura Baudis (University of Zurich)

Abstract: 

We are experimentally investigating possible departures from the standard quantum mechanics’  predictions at the Gran Sasso underground laboratory in Italy.

 In particular, with radiation detectors we are searching signals coming from collapse models (spontaneous emission of radiation) which were proposed to solve the “measurement problem” in quantum physics and signals related to a possible violation of the Pauli Exclusion Principle. 

I shall discuss our recent results, published in Nature Physics under the title “Underground test of gravity-related wave function collapse”, where we ruled out the natural parameter-free version of the gravity-related model.  I shall then present more generic results on testing CSL (Continuous Spontaneous Localization) collapse models and future perspectives, both from experimental and theoretical points of view.

Finally, I shall present the VIP experiment where we test possible violations of the Pauli Exclusion Principle by searching for “impossible” atomic transitions and discuss the impact of this research.
