Bose-Einstein condensation in the relativistic ideal Bose gas.
The Bose-Einstein condensation (BEC) critical temperature in a relativistic ideal Bose gas of identical bosons, with and without the antibosons expected to be pair-produced abundantly at sufficiently hot temperatures, is exactly calculated for all boson number densities, all boson point rest masses, and all temperatures. The Helmholtz free energy at the critical BEC temperature is lower with an...
متن کاملThe Ideal Bose — Einstein Gas , Revisited
Some questions concerning the ideal Bose—Einstein gas are reviewed and examined further. The bulk behavior including the condensation phenomenon is characterized by the thermodynamical properties, occupations of the states and their fluctuations, and the properties of the density matrices, including the diagonal and off-diagonal long range orders. Particular attention is focused on the differen...
متن کاملCondensate fluctuations of a trapped, ideal Bose gas.
For a non-self-interacting Bose gas with a fixed, large number of particles confined to a trap, as the ground-state occupation becomes macroscopic, the condensate number fluctuations remain microscopic. However, this is the only significant aspect in which the grand canonical description differs from canonical or microcanonical in the thermodynamic limit. General arguments and estimates includi...

متن کاملN ov 2 00 5 Thermodynamic properties of a trapped Bose gas : A diffusion Monte
We investigate the thermodynamic properties of a trapped Bose gas of Rb atoms interacting through a repulsive potential by Quantum Monte Carlo method. Our method is 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 temperature variation of condensation fraction, chemical potential, density profile, tota...
