Abstract
We measure the population distribution in one of the atomic twin
beams generated by four-wave mixing in an optical lattice. Although the
produced two-mode squeezed vacuum state is pure, each individual mode is
described as a statistical mixture. We confirm the prediction that the
particle number follows an exponential distribution when only one
spatio-temporal mode is selected. We also show that this distribution
accounts well for the contrast of an atomic Hong–Ou–Mandel experiment.
These experiments constitute an important validation of our twin beam
source in view of a future test of a Bell inequality.
