Vibrational state inversion of a Bose-Einstein condensate: optimal control and state tomography
arXiv:1212.4173 · doi:10.1088/0953-4075/46/10/104012
Abstract
We present theoretical and experimental results on high-fidelity transfer of a trapped Bose-Einstein condensate into its first vibrationally excited eigenstate. The excitation is driven by mechanical motion of the trap, along a trajectory obtained from optimal control theory. Excellent agreement between theory and experiment is found over a large range of parameters. We develop an approximate model to map the dynamics of the many-body condensate wave function to a driven two-level system.
