Abstract
- We study the behavior of ultracold bosonic gases in the critical region above the Bose-Einstein condensation in the presence of an artificial magnetic field, Bart. We show that the condensate fluctuations above the critical temperature Tc cause the fluctuational susceptibility, χfl, of a uniform gas to have a stronger power-law divergence than in an analogous superconducting system. Measuring such a divergence opens new ways of exploring critical properties of ultracold gases and an opportunity for an accurate determination of Tc. We describe a method of measuring χfl which requires a constant gradient in Bart and suggest a way of creating such a field in experiment. [ABSTRACT FROM AUTHOR]
