Numerical solution of the MCT schematic model B in the glassy phase (red continuous line), with λ = 0.5.
Dashed line is the power law t−a, with a = 0.40, obtained from Eq. (20). The data are in excellent agreement with the cluster approach prediction (dotted line is the stretched exponential-like decay, Eq. (11), with c = 0.45 and y = 0.54, obtained using x = 1/3a = 0.84).
