Critical Temperature and Ground State Fraction of a Weakly Interacting Bose Gas Trapped in a Harmonic Potential
Lixuan Chen
Abstract
The critical temperature for the Bose-Einstein Condensation of an imperfect Bose gas trapped in a harmonic potential is calculated by using the local density approximation (LDA). The effects of weak interaction on the critical temperature and ground-state fraction of particles are discussed. The investigation will be helpful for the further understanding of the properties of BEC, which is called as a new kind of state of matter.
