Figure 4.

Semi-log plot of the normalized distribution P(x, t) with variables x (nm) and t (s). This histogram uses the experimental data of fig. 4(a) in [8]. The three lines show the q-Gaussian distributions of equation (2.9): $\hat{\alpha }=0.53$ for the dashed line, $\hat{\alpha }=0.57$ for the solid line and $\hat{\alpha }=0.59$ for the dotted line [8]. $|x|\le 500\hspace{0.17em}\mathrm{nm}$ and $t=9.2\mathrm{s}$ are considered.
