Degenerate Bose Gas: A New Tool for Accurate Frequency Measurement
arXiv:1309.0181
Abstract
We propose a new way of detecting frequencies using superradiant Rayleigh scattering from degenerate Bose gases. A measurement of the time evolution of population at the initial momentum state could determine an unknown frequency with respect to a known one at which the pump laser's frequency modulates. A range of frequencies from kHz to MHz could be determined with a fractional uncertainty of 10^{-6}.
