| dc.description | We investigate the thermodynamic properties of a trappoed Bose gas of Rb atoms interacting through a repulsive potential by Quantum Monte Carlo method based upon the generalization of Feynman-Kac method[1] applicable to many body systems at T=0 to finite temperatures. In this letter,we report the temperature variation of condensation fraction, chemical potential,density profile, total energy of the system, release energy, frequency shifts and moment of inertia within the realistic potential (Morse type) for the first time by diffusion Monte Carlo technique. The most remarkable success was in achieving the same trend in the temperature variation of frequency shifts as was observed in JILA[2] for m=2 and m=0 modes . For other things we agree with the work of Giorgini et al[3] Pitaevskii et al[4] and Krauth[5] | |
