Abstract

In this work the eect of the potential parameters on the condensate fraction and the critical temperature ofneutral many-bosonic system are investigated. A many-body technique called the static uctuation approximationis used in this study. The interaction potential is modeled by two linear terms. The condensation fraction andcritical temperature were found to decrease with increasing the strength or the range of the repulsive part of thepotential. On the other hand, the condensation fraction and critical temperature increase with increasing thedepth or range of the attractive part of the potential.ACS:P 67.10.Ba, 67.25.bd, 51.30.+i
