    • This type of generalization has been used by Yu. Kagan and L. A. Maksimov, Laser Phys. LAPHEJ 1054-660X 12, 106 (2002), to study the damping of the radial breathing mode of an elongated condensate without optical lattice. Within their approach, the damping at zero temperature originates from the parametric amplification of longitudinal phonons out of quantum fluctuations.

The purpose of this work was the observation of a period-doubling instability analogous to similar dynamical instabilities in a condensate moving in an optical lattice. In addition to the period-doubling instability, an unexpected type of excitations was observed at higher modulation frequency. We guess that this could be the result of the parametric resonance at the frequency \par\par\par890\par+\par891\par\par\par, which is the lowest one allowed by the symmetry of the problem.
