(a) Intensity autocorrelation function minus one measured as a function of time. (b) Ratio of the characteristic times obtained from the analysis of the autocorrelation functions shown in (a) normalized by the initial decay time measured at t = 0h. Line is a fit to a critical power law: , where τ₀ is the decay time of the autocorrelation at time t =0 h and and s are fitting parameters.
