Two-step condensation of the charged Bose gas.
The condensation of the spinless ideal charged Bose gas in the presence of a magnetic field is revisited. The conventional approach is extended to include the macroscopic occupation of excited kinetic states lying in the lowest Landau level, which plays an essential role in the case of large magnetic fields. In that limit, signatures of two diffuse phase transitions (crossovers) appear in the s...
متن کاملBose}Einstein condensation of noninteracting charged Bose gas in the presence of external potentials
We investigate thermodynamic properties of noninteracting charged bosons in the presence of externally applied electric and magnetic "elds. Using the semiclassical density of states, we obtain the condensate fraction, chemical potential, total energy, and speci"c heat of a system of "nite number of charged Bose particles. We conclude that Bose}Einstein condensation of the charged Bose gas occur...
متن کاملTwo-step condensation of the ideal Bose gas in highly anisotropic traps
The ideal Bose gas in a highly anisotropic harmonic potential is studied. It is found that BoseEinstein condensation occurs in two distinct steps as the temperature is lowered. In the first step the specific heat shows a sharp feature, but the system still occupies many one-dimensional quantum states. In the second step, at a significantly lower temperature, the ground state becomes macroscopic...
متن کاملBose-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 کاملMulti-step Bose-Einstein Condensation of Trapped Ideal Bose Gases
The Phenomenon of multi-step Bose-Einstein condensation (BEC) of a finite number of non-interacting bosons in anisotropic traps has been demonstrated by studing the populations on eight subsets of states. The cusp in the specific heat is found to be associated with the crossover between subsets of states involving Bose functions gn(z) of different classes, as specified by their behaviour at z =...
