Asymptotic solutions to the Gross-Pitaevskii gain equation: growth of a Bose-Einstein condensate
P. D. Drummond, K. V. Kheruntsyan
Abstract
We give an asymptotic analytic solution for the generic atom-laser system with gain in a D-dimensional trap, and show that this has a non-Thomas-Fermi behavior. The effect is due to Bose-enhanced condensate growth, which creates a local density maximum and a corresponding outward momentum component. In addition, the solution predicts amplified center-of-mass oscillations, leading to enhanced center-of-mass temperature.
