Correlators in MCT schematic model B.
Each curve corresponds to a different value of ϵ. The correlator reaches the plateau with a power law decay, Φ(t) − mc ~ t−a and the departure from the plateau is given by Φ(t) − mc ~ −(t/τβ)b. At long times, a crossover is observed to a new regime, well fitted by stretched exponential function.
