Contribution

It introduces a new practical approach to estimate condensate fractions considering interactions and trapping potentials in Bose gases.

Findings

Condensate fraction decreases exponentially with increasing scattering length.

The method accounts for temperature and interaction effects in trapped Bose gases.

Provides a tool for experimental and theoretical analysis of Bose-Einstein condensates.

Abstract

We suggest a practical way to estimate the condensate fraction of an interacting dilute Bose gas confined by an external harmonic potential as a function of temperature and scattering length. It shows that an increase of the scattering length produces an exponential decrease of condensate fraction.
