Canonical Ensemble Redefined - 3. Ideal Bose Gas

摘要

The ideal Bose gas solved in the redefined ensemble formalism exhibits a discontinuity in the specific heat suggesting that Bose-Einstein condensation is a second order phase transition. The deviations from the classical ideal gas behaviour are larger than those predicted by Gibbs ensemble. Below Tsub(c) the pressure is not independent of the volume. For a certain range of values of VT sup 3 , the peak in black body radiation shows a shift in the frequency scale and this could be detected, at least in principle, experimentally.
