(a) The decay of the coherent scattering function as a function of the time rescaled by the relaxation time τ_q for a wave vector ranging from q=0.1 to 10 and for three different ratios of k_BT/∈. (b) The exponent β as a function of the wave vector q, showing a transition from a compressed to a stretched dynamics. (c) The particle MSD as a function of time t for the same k_BT/∈ ratios as in a. (d) The relaxation time τ(q) as a function of the wave vector q for the three systems: the scaling goes from τ∼q⁻¹ for the fully athermal regime to diffusive τ∼q⁻² when the thermal fluctuations dominate; a plateau emerges at low wave vectors corresponding to distances beyond the mesh size of the network, as sketched in the cartoons.
