Quantitative analysis of the homogeneous expansion for different times and setups.
(a), (b), (c): Density as a function of radius only. The magnification in (a) details the cloud anisotropy. The inset legend also applies to the rest of (a). The legend in (b) is shared with (c). (d): Rmax (solid lines) and Rrms (dashed-dotted lines). For U = 8, sudden expansion, fits are shown (dashed lines). (e): Rmax for U = 24 as a function of rescaled time t/Ï„. Densities for different trap protocols (Ï„ = 70, 80, 90) have distinct symbols; different density domains have distinct colours. (f): Bond currents and densities in the z = 0 plane for U = 24, t = 30. Blue (red) arrows correspond to large (intermediate) currents, whilst small currents are not shown.
