Time-dependent condensate fraction in an analytical model

We apply analytical solutions of a nonlinear boson diffusion equation (NBDE) that include boundary conditions at the singularity to calculate the time evolution of the entropy during evaporative cooling of ultracold atoms, and the time-dependent condensate fraction. For suitable initial conditions i...

Zusammenfassung:We apply analytical solutions of a nonlinear boson diffusion equation (NBDE) that include boundary conditions at the singularity to calculate the time evolution of the entropy during evaporative cooling of ultracold atoms, and the time-dependent condensate fraction. For suitable initial conditions it is found to agree with available data on 23Na.
