Abstract
The paper studies the dynamics of a Bose-Einstein condensate loaded in a 1D parabolic optical lattice and excited by a sudden shifting of the lattice center. Depending on the initial shift, this dynamics is either the dipole or Bloch oscillations of the atoms. The effects of the dephasing and atom-atom interactions on the above atomic oscillations are discussed.

Rigorously this result follows from the quadratic dependence for the eigenenergies of the quantum pendulum in the asymptotic region l ≫ l*.

In the considered case of a finite wave packet it looks reasonable to associate n with the number of atoms N devided by the wave packet width γ.
