| Figure 5. Time evolution of Czz with four typical models. Yellow, blue, purple, and green lines correspond to fixed locations l = 1, 2, 3, 4, respectively. Czz at (γ = 1, λ = 0) vanishes for l > 1. The dashed lines are used to show power law fitting. We can see clearly from the figures that these models show t4l − 2 and t2l power law growth at early time, and t−1 decay at late-time, independent of site l. |
