Correction to Critical Point of Symmetric Binary Homopolymer Blends

In some of the field-theoretic simulations (FTS) from our paper, the Monte Carlo (MC) move that changes the average value of the W−(r) field was accidentally disabled, leading to poor statistics. Only a few of the results are significantly affected, but one of the main conclusions of the paper has changed. Here the simulations are repeated with the MC move enabled and a new semi-grand canonical ensemble that helps increase the computational speed and accuracy. Figure 3 shows the corrected cumulant calculations. The data for N̅ = 10 and 10 are close to those in the original paper; however, there is a notable difference in the crossing point for N̅ = 10. The collapse of the scaled curves, shown in Figure 4, is somewhat better than in the original paper, as a result of the improved statistics.
