Relativistic ideal Bose gas in Harmonic traps
Abstract
Using semiclassical approximation method, Bose-Einstein condensation (BEC) of a relativistic ideal boson gas (RIBG) with and without antibosons in three-dimensional (3-D) harmonic traps is investigated. The BEC transition temperature Tc and the Helmholtz free energy at Tc are calculated. The effect of the rest mass of the boson on the properties of the system is also studied. We find that Tc of RIBG is higher than that of the nonrelativistic approximation. The RIBG with antibosons is also investigated and it is found that the Helmholtz free energy of the system with antibosons at Tc is lower than that of the system without antibosons. It implies that the system with antibosons is more stable.
