Fig. S2.

Correlation $⟨\mathcal{C}⟩$ and $\xi$ vs. the time interval $\mathrm{\Delta }t$ at variable $c_{\text{TTAB}}$. The fit of $\xi$ to our analytical model (Eq. S4) and the corresponding function for $⟨\mathcal{C}⟩$ are shown as black dashes. As our model is not applicable for small $\mathrm{\Delta }t$, the data points marked in red were not used in the parameter fit. Data were binned by $\mathrm{\Delta }t$, using $100$ events per bin, and then averaged (the corresponding $\mathrm{\Delta }t$ range is marked by the bar width). By fitting $\xi$ using Eq. S4, we obtain for $c_{\text{TTAB}}=5$ wt% the parameters $a=-5.3\pm 0.3$ and $b=(6.3\pm 2.5)\times {10}^2\text{s}$, and for $c_{\text{TTAB}}=7.5$ wt% the parameters $a=-3.6\pm 0.2$ and $b=(4.3\pm 1.2)\times {10}^2\text{s}$. We provide no fit for $c_{\text{TTAB}}=10$ wt% due to insufficient statistics in the long time limit.
