Figure 3. Time evolution of the order parameter for larger density difference between the lighter (${\rho }_{l}=1.0\,{\rm{g}}\,{\mathrm{cm}}^{-3}$) and heavier (${\rho }_{h}=20.0\,{\rm{g}}\,{\mathrm{cm}}^{-3}$) particles at a series of fixed vibration amplitude. The circles, diamonds, upward-pointing triangles, downward-pointing triangles and leftward-pointing triangles are for Γ = 19.2, 16.0, 12.8, 8.0 and 4.8, respectively. The open and closed symbols are for the simulations started from a completely mixed initial state and a pure separated initial state, respectively.
