Abstract: |
We show how to apply the scaling theory in an inhomogeneous system
like harmonically trapped Bose condensate at finite temperatures. We
calculate the temperature dependence of the critical number of
particles by a scaling theory within the Hartree-Fock approximation
and find that there is a dramatic increase in the critical number of
particles as the condensation point is approached. Our results support
the experimental result which was obtained well below the condensation
temperature.
