3 Jan 2013 | | Abstract: | We propose an experiment for the measurement of gravitational effect on cold
atoms by applying a one-dimensional vertically sinusoidal oscillation to the
magneto-optical trap; and observe the signature of low quantum energy shift of
quantum bound states as a consequence of gravitational fluctuation. To this
end, we present brief details of the experiment on a BEC, and a simplistic
calculation of the Gross-Pitaevskii solution using Thomas-Fermi approximation
with focus on the density of the BEC, for the time-dependent perturbation.
Moreover, we calculate the power induced by quantum gravity on a generic atomic
ensemble. We Also address the possible challenges for the measurement of the
expected results. And, finally, we discuss the prospect of further developing
this experiment towards measuring the effect of quantum spacetime fluctuations
on cold atoms. | | Source: | arXiv, 1301.0494 | | Services: | Forum | Review | PDF | Favorites | |
