Phys. Rev. Lett. 87, 210401 (2001) [4 pages]Bose-Fermi Variational Theory of the Bose-Einstein Condensate Crossover to the Tonks GasReceived 26 June 2001; revised 10 October 2001; published 31 October 2001 A number-conserving hybrid Bose-Fermi variational theory is developed and applied to investigation of the Bose-Einstein condensate crossover to the Tonks gas in toroidal and long cylindrical traps of high aspect ratio, where strong many-body correlations and condensate depletion occur. © 2001 The American Physical Society URL:
