New avenues for testing collapse models

New avenues for testing collapse models
New avenues for testing collapse models
There is an increasing interest in developing experiments aimed at testing collapse models, in particular the Continuous Localization Model (CSL), the natural evolution of the GRW model initially proposed by Ghirardi et al. Current experiments and related bounds on collapse parameters are partially discussed in other contributions in this review. Our aim here is to discuss some of the most promising directions towards future improvements. The paper is organized as follows. In Sections II, III, IV we will discuss non-interferometric techniques. In detail, in Section II we will discuss mechanical experiments, both with conventional and levitated mechanical resonators, in Section III we will consider proposed experiment looking at bulk thermal heating of solid bodies and in Section IV we will briefly discuss the use of cold atoms or macroscopic condensates. In Section V we will outline proposals of matter-wave interference with massive nano/microparticles. We will end in Section VI with some ideas on how precision experiments can be used for testing collapse models.

Abstract

There is an increasing interest in developing experiments aimed at testing collapse models, in particular the Continuous Localization Model (CSL), the natural evolution of the GRW model initially proposed by Ghirardi et al. Current experiments and related bounds on collapse parameters are partially discussed in other contributions in this review. Our aim here is to discuss some of the most promising directions towards future improvements. The paper is organized as follows. In Sections II, III, IV we will discuss non-interferometric techniques. In detail, in Section II we will discuss mechanical experiments, both with conventional and levitated mechanical resonators, in Section III we will consider proposed experiment looking at bulk thermal heating of solid bodies and in Section IV we will briefly discuss the use of cold atoms or macroscopic condensates. In Section V we will outline proposals of matter-wave interference with massive nano/microparticles. We will end in Section VI with some ideas on how precision experiments can be used for testing collapse models.
