    • F =0). In contrast to recent investigations which verified the predicted F= 1 energetic ground state [14,34] we start with T>0 and unfavorable initial populations with respect to the ground state. Damping of spin dynamics due to finite temperature and magnetic field may explain this discrepancy.

    • note
    • Numerical simulations of a set of coupled Gross-Pitaevskii equations turned out to be cumbersome as they crucially depend on initial phases [30]. The considerable effect of spin dynamics here is the production of |0 atoms. The introduction of two rates following the law of mass action is a simple approximation for spin dynamics reaching a (nonequally distributed) steady state.
