    • note
    • We have also used a 2D fitting distribution made of a Gaussian profile for the thermal component and a Thomas-Fermi profile for the condensate. This gave the same result for the scissors angle, confirming that this is not affected by the choice of the model used to describe the cloud profile. The condensate fraction was instead systematically lower than about 10% compared to the Gaussian profile fitting.

    • note
    • The calculation of both the frequency and the damping rate as a function of T requires detailed knowledge of the frequencies of all the significant fundamental modes of the condensate which mix with the mode under study. Such calculations are being carried out for the scissors mode by extending the finite T theory of the BEC developed by Rusch et al. [20] to the case of the TOP trap (rather than a spherically symmetric potential).
