Abstract

We investigate the statistical distribution for ideal Bose gases with constant particle density in the 3D box of volume V=L3V=L^{3}. By changing linear size LL and imposing different boundary conditions on the system, we present a numerical analysis on the characteristic temperature and condensate fraction, and find that the smaller linear size is efficient to increase the characteristic temperature and condensate fraction. Moreover, there is a singularity under the antiperiodic boundary condition.
