FIG. 3.

The many-particle survival probabilities ${\mathcal{S}}^{\rho =1}\left(t\right|\text{eq}),{\mathcal{S}}^{\rho =\Theta }\left(t\right|\text{eq})$ corresponding to the two different initial conditions (Eqs. (41) and (38) respectively). The chosen parameters are D = 0.25, a = 1, κ_r = 10, a = 1, L = 10. The solid lines refer to the analytical expressions (Eqs. (60) and (69)), the markers indicate the simulation results.
