Hi Carnot, I know this response is coming in a bit late, but better late than never.. TOP traps are useful for making Bose-Einstein Condensates with alkali atoms. Normally you start with a magneto-optical trap (MOT) and then evaporate the atoms for the next stage in cooling. MOT's generally...

For a physical explanation, you could consider long wavelength phonons destroying the coherence in an infinite system. However, in a real system, finite size effects give a lower bound on the phonon energy and so it requires more energy for a phonon to show up and start tearing the condensate...
