Quantum Interference and the Trapped Bose Condensed System
Abstract
In experiments involving Bose condensed atoms trapped in magnetic bottles, plugging the hole in the bottle potential with a LASER beam produces a new potential with two minima, and thus a condensate order parameter (i.e. wave function) with two maxima. When the trapping potential is removed and the condensate explodes away from the trap, the two wave function maxima act as two coherent sources which exhibit amplitude interference. A simplified theoretical treatment of this experimental effect is provided by considering momentum distributions.
