Dipole and Bloch oscillations of cold atoms in a parabolic lattice
arXiv:cond-mat/0509322 · doi:10.1134/S1054660X06020289
Abstract
The paper studies the dynamics of a Bose-Einstein condensate loaded into a 1D parabolic optical lattice, and excited by a sudden shift of the lattice center. Depending on the magnitude of the initial shift, the condensate undergoes either dipole or Bloch oscillations. The effects of dephasing and of atom-atom interactions on these oscillations are discussed.
