Figure 2: Full probability distributions of ρ0.
Evolution on the semi-classical phase space (left column) and histograms of the measured spin population, ρ0 (right) for different evolution times after the quench, 15, 130, 140, 170 and 240 ms. (a) The simulations use the semi-classical equations of motion together with a quasi-probability distribution for the initial state. The mean value for ρ0 and θs are indicated with a black dot. (b) The histogram bars for each evolution time depict the measured probability density of ρ0 for over 900 experimental runs, and the red line represents the simulation. The purple bar in each histogram represents the bin in which the mean of ρ0 is located.
