    • Although we could not overcome metastability of this model in direct simulations, we observed that the droplet nucleation mechanism must be effective. That is, when we start the simulations with the thermodynamically unstable phase with a sufficiently large droplet of a stable phase injected “artificially” at the beginning, then this droplet might divert the evolution toward the stable phase. Without such a droplet the unstable phase remains in its state virtually forever. Moreover, the minimal size of such droplets is rather large, which suggests that their spontaneous nucleation is an extremely unlikely event
