Description

We compute the density-density correlation function near an acoustic horizon realized in a Bose-Einstein condensate.
A correct normalization of the field of Bogoliubov excitations necessitates to account for the contribution of zero modes.
Once this is achieved, one obtains a very good description of the recent experimental results of Technion's group.
