Query: Bose-Einstein Condensation in Anisotropic Harmonic Traps   We study the thermodynamic behaviour of an ideal gas of bosons trapped in a
three-dimensional anisotropic harmonic oscillator potential. The condensate
fraction as well as the specific heat is calculated using the Euler-Maclaurin
approximation. For a finite number of particles there is no phase transition,
but there is a well defined temperature at which the condensation starts. We
also consider condensation in lower dimensions, and for one-dimensional systems
we discuss the dependence of the condensate fraction and heat capacity on the
ensemble used.
