Abstract
The exact many-body wave function obtained with the Fermi-Bose mapping theorem was used to investigate the ground-state properties of a system of hard-core bosons in a 1D HO. Monte Carlo integration for particle numbers up to N=10 was used to evaluate the reduced single-particle density matrix for the system. In the case of a true Bose-Einstein condensate, it was found that the occupation of the lowest orbital varied as N0.59, in contrast to N0.5.
