FIG. 1.

Time evolution of the density profile in the monodisperse case for . The -enhanced and -depleted bumps appear, which can be explained by symmetry.

FIG. 2.

The broadening of interface with respect to time for different in the monodisperse case. The interfacial width, , is scaled by the equilibrium width, . It shows that at early time the interfacial widths broaden fast, and they saturate to the equilibrium ones at quite long time.

FIG. 3.

Data from Fig. 2 plotted in a scaled form. Both the interfacial width and the time are scaled by . The data approximately collapse onto a single master curve. At an early time, the broadening of the scaled interfacial width obeys a power law with the power index is about 0.38.

FIG. 4.

The evolution of the scaled interface with respect to time in the polydisperse case for different and different polydispersities.

Image of FIG. 5.
FIG. 5.

Data from Fig. 4 plotted in a scaled form. (a) The time is scaled by for , (b) by for , and (c) by for . The data approximately collapse onto a single master curve for different polydisperse case. At early time, the power index is about 0.38 which is independent of the polydispersity.
