Bose-Einstein Condensates: Theory

Alexander Jurisch, Jan Michael Rost

We develop a quasi-analytical theory for the quantum reflection amplitude of Bose-Einstein condensates. We derive and calculate the decay-width of a Bose-Einstein condensate. A general relation between the time-dependent decay-law of the system and its quantum reflection amplitude allows us to explain the quantum reflection anomaly of Bose-Einstein condensates present in BEC-surface systems as a direct consequence of the repulsive particle interaction.

On the basis of the analysis of the conditions for producing BEC and the generalization of several successful experiments on Bose-Einstein condensation, such idea is produced that the experimental conception on the production of two-dimensional Bose-Einstein condensation can be realized by ideal gas under limited conditions.
