Fig. 3. An entropic barrier hinders droplet coalescence and drives the metastability of a two-droplet state.

Fig. 3

a Free energy profile as a function of the radius of gyration (Rg) that effectively measures the distance between two droplets. Energetic (black) and entropic (red) contributions to the free energy profile before (c) and after (b) the coalescence barrier. Error bars were calculated as standard deviations of the mean using block averaging by dividing the simulation trajectories into five blocks of equal length.
