Testing Wavefunction Collapse Models using Parametric Heating of a Trapped Nanosphere | Daniel Goldwater

29 Jun 2015 | Abstract: | 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 {f 40} 2935 (2006)] and Bassi
[EPL {f 92} 5006 (2010)] ought to be testable using this scheme. | Source: | arXiv, 1506.8782 | Services: | Forum | Review | PDF | Favorites |
