Figure 1: Time evolution of spin populations.

From: Non-equilibrium dynamics of an unstable quantum pendulum explored in a spin-1 Bose–Einstein condensate

Figure 1

Probability density of the fractional population of the condensate in the mf=0 state, ρ0, as a function of time. The curves show the mean, (black line) and± σ (blue lines). (a) Experimental data showing the results of 50 runs at each evolution time placed into 40 bins. The mean and σ curves have been smoothed using a cubic spline. (b) Quantum calculation using the initial atom number, magnetic field ramp and atom loss rate measured in the experiment. The Fock state probabilities |cp|2, placed into 100 bins, are plotted.
