Abstract
- We review the properties of chaoticity and coherence in Bose-Einstein condensation and correlations, for a dense boson system in its mean-field represented approximately by a harmonic oscillator potential. The order parameter and the nature of the phase transition from the chaotic to the condensate states are studied for different fixed numbers of bosons. The two-particle correlation function in momentum space is calculated to investigate how the Bose-Einstein correlation depends on the degree of condensation and other momentum variables. We generalize the Bose-Einstein correlation analysis to three-particle correlations to show its dependence on the degree of condensation.<br />Comment: 17 pages, 8 figures, invited talk presented at the Xth Workshop on Particle Correlations and Femtoscopy (WPCF14) at Gyongyos, Hungary on August 25 to 29, 2014
