We present the results of the systems quenched to a reduced temperature of 0.75. Each set of results have been averaged over two different initial configurations. You may view the overall results for each initial configuration: set 1, set 2.

#1: "old" k1 vs. "new" k1: using phi-based S(k).
"old" k1: R ~ t1/2 --> t1/3; "new" k1: R ~ t1/3 --> slower than t1/3.
We focus on our "new" k1 results. Initially, domain growth appears to have a t1/3 growth law (Model B). Growth slows down around t=20, but PS and PO both well-established by t=5. What causes the slowing down? Should we even get t1/3 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. But why don't we see this "intermediate" behavior for quenches that are unstable wrt PS and PO, but more unstable wrt PO? Maybe the rate at which ordering occurs becomes faster than the rate at which PS occurs at t~20, causing domain growth to slow down. This would not be observed in quenches like E7-2 (unstable wrt PS and PO, but more unstable wrt PO), since for such a quench, the rate at which ordering happens already exceeds the rate at which PS happens. How can we check this?
Note: Initial growth behavior is actually slightly faster than t1/3. (See below.)

Domain growth slower than t1/3 immediately; no "intermediate" t1/3 behavior. Significant ordering from the start causes domain growth to slow down from the start.
Although our calculated power law produces a good fit to our data, this system does not exhibit true scaling behavior, except maybe towards the end of this time frame.
