Effects of Externally Applied Electric and Magnetic Fields on Bose- Einstein Condensation of Charged Bose Gas

Abstract

We have studied the effects of the externally applied electric and magnetic fields onBose-Einstein condensation of the charged Bose gas. We have used a model densityof states which takes the finite sample size into account to calculate thethermodynamic quantities. We have obtained condensate fraction, chemicalpotential, total energy and specific heat of the system using the semi classical densityof states. We have studied the possibility for achieving Bose-Einstein condensationin three dimensional non interacting charged Bose gas under the cross electric andmagnetic fields. The external fields made the system inhomogeneous and altered theBose-Einstein condensation characteristics compared to the homogeneous case. Wehave found that the non interacting system of charged boson undergo Bose- Einsteincondensation when external electric and magnetic fields were applied. Thediscontinuity in the specific heat was found as a function of external potentials. Theobtained results were found in good agreement with previously obtained results.
