  We study the correlation functions of scalar operators in the theory defined
as the holographic dual of the Schroedinger background with dynamical exponent
z=2 at zero temperature and zero chemical potential. We offer a closed
expression of the correlation functions at tree level in terms of Fourier
transforms of the corresponding n-point functions computed from pure AdS in the
lightcone frame. At the loop level this mapping does not hold and one has to
use the full Schroedinger background, after proper regularization. We
explicitly compute the 3-point function comparing it with the specific 3-point
function of the non-relativistic theory of cold atoms at unitarity. We find
agreement of both 3-point functions, including the part not fixed by the
symmetry, up to an overall normalization constant.
