Fig. 4, panel (a)

Spin-squeezing parameter $\xi^2$ against time $t\kappa$, on a logarithmic $\xi^2$ axis, for the unconditional dynamics with $N = 110$, $\epsilon = g/\kappa = 0.017$ and $d = 2\delta/\kappa = 1.0$: Full dynamics (solid), 2nd order (dotted) and 3rd order (dot-dashed). The horizontal dashed line is the standard quantum limit (SQL).
