Query: Cosmic Dynamics of Bose-Einstein Condensates   A dynamical correspondence is established between positively curved,
isotropic, perfect fluid cosmologies and quasi-two-dimensional, harmonically
trapped Bose-Einstein condensates by mapping the equations of motion for both
systems onto the one-dimensional Ermakov system. Parameters that characterize
the physical properties of the condensate wavepacket, such as its width,
momentum and energy, may be identified with the scale factor, Hubble expansion
parameter and energy density of the universe, respectively. Different forms of
cosmic matter correspond to different choices for the time-dependent trapping
frequency of the condensate. The trapping frequency that mimics a
radiation-dominated universe is determined.
