Self-consistent hydrodynamic one-loop quantum corrections to the Gross-Pitaev-skii equation due to the interaction of the condensate with collective excitations are calculated. It is done by making use a formalism of effective action and ζ-function regularization for a contribution from Bogoliubov particles in hydrodynamic approximation. It turns out to be… CONTINUE READING
