Figure 5.

(a–d) Stability diagrams for $\left(0.5,0.5\right)$ overall composition, for varying indirect and direct couplings J and B and values of the length-independent interaction strength V and mismatch ${\text{Δ}}_0$. Thick lines and bold labels indicate where the equilibrium state is R-R, AR-AR, or mixed. Thin lines denote where the bilayer is unstable to R/AR modes and are labeled on the side of the line to which they refer. The secondary (right) axis indicates approximate values of the interleaflet mismatch free energy per area γ (Eq. C6). Colors indicate growth rates from linear stability analysis of the initial homogeneous state, $\text{Δ}\omega >0$ (R mode faster (blue)) and $\text{Δ}\omega <0$ (AR faster (red)). Different color scales are used for visibility, since comparison of growth rates between different panes of the figure has little meaning. In (c), the color range is reduced five times from that indicated on (d). The green dots in (b) correspond to Fig. 4, and that in (c) corresponds to Fig. 2. (e and f) Illustrative q-dependent growth rates. To see this figure in color, go online.
