摘要
We propose a mechanism for testing the theory of continuous spontaneous localization (CSL) by examining the parametric heating rate of a trapped nanosphere. The random localizations of the centre of mass for a given particle predicted by the CSL model can be modelled as a stochastic force embodying a source of heating for the nanosphere. We show that by utilising a Paul trap to levitate the particle coupled with optical cooling, it is possible to reduce environmental decoherence to such a level that CSL dominates the dynamics and contributes the main source of heating. We show that this approach allows measurements to be made on the timescale of seconds, and that the full parameter ranges given by Adler [J. Phys. A {bf 40} 2935 (2006)] and Bassi [EPL {bf 92} 5006 (2010)] ought to be testable using this scheme.
