F21-2 Run: phi0=0.84 T=0.75 N=150

Initially unstable with respect to PS and PO, but more unstable with respect to PS.

Morphology: At early times, system contains many small polymer-rich droplets. Many coalesce and form very long (but not thin and fibrillar) domains. At late times, these polymer-rich domains shorten. Some are worm-like (but not thin!), while others are almost circular ("circular with kinks").

Resulting intermediate/late-time structure: Elongated and noncircular polymer-rich domains (minor phase) in a LC-rich matrix (major phase). View phi and S profiles.

Evolution of degree of PS and PO.
for PS (red): delta_phi(t) = phi_max(t) - phi_min(t)
for PO (blue): S(t) = S_max(t)
Plot indicates that PS and PO are significant at t~6. phi and S profiles reveal that these times (at which this plot indicates a high degree of PS and PO) represent when PS and PO begin to be significant. (That is, there is at least one or two small regions that have strongly phase separated or ordered.)
For this quench, PS is well-established by t=6. Furthermore, PO is quite significant at t=6 and becomes well-established by t=8.

#1: new" k₁ -- from phi-based S(k).
Initially, R ~ t^1/2 - t^1/3.
At t~30, domain growth slower than t^1/3.
Initially, domain growth appears to have a t^1/3 growth law (Model B). Growth slows down around t=30, but PS and PO both well-established by t=6. What causes the slowing down? Should we even get t^1/3 behavior? Perhaps the initial behavior is transient and the only significant result is the eventual slowing down of domain growth due to the coupling of PS and PO. Why don't we see this "intermediate" behavior for quenches that are unstable wrt PS and PO, but more unstable wrt PO?
Also, data for t>50 may not be reliable. At t=48, there are only four domains left!
Note: Initial growth behavior is actually slightly faster than t^1/3, and we get similar behavior for the C2-1 (phi0=0.85, T=0.75, N=150) quench. Recall that C2-1, like this quench, is unstable wrt PS and PO, but more unstable wrt PS.
