Fig. 1: Behavior of the whole system and free energy landscape.

a Time evolution of the number of smectic molecules in the system. The number of smectic molecules belonging to the largest smectic cluster is also plotted. b Time evolution of numerical X-ray scattering intensity. The intensity as a function of the number of smectic molecules in the system is also plotted. c Contour map of free energy landscape as a function of smectic cluster size and order parameter value. The black lines indicate contours with interval of 0.5 kBT. d Estimated value of the nucleation rate as a function of the threshold size. J1 and J2 are plateau values. e Free energy minima as a function of the cluster size.
