K. Kirsten et Dj. Toms, DENSITY-OF-STATES FOR BOSE-EINSTEIN CONDENSATION IN HARMONIC-OSCILLATOR POTENTIALS, Physics letters. A, 222(3), 1996, pp. 148-151
We discuss how it is possible to obtain a reliable approximation for t
he density of states for a system of particles in an anisotropic harmo
nic oscillator potential. A direct application of the result to study
Bose-Einstein condensation of atomic gases in a potential trap can be
given. In contrast to a previous study, our method involves only analy
tic calculations.
