Phase diagram bimodal line

Fig. 1.9 Calculated polymer-solvent phase diagram. The bimodal (continuous line) is the coexistence curve the points below it correspond to thermodynamically unstable states, which undergo phase separation. However, the pints between the bimodal and the spinodal (dashed line) are ki-netically stable, since there is a free-energy barrier to phase separation. C indicates the critical point the collapse temperature. The deviation of the low-concentration branch of the spinodal from the vertical axis below T is an artifact of the mean-field approximation. (From ref. [62])...

Dynamic Density Functional Theory (DDFT), Fig. 2 Schematic phase diagram of a system of Brownian particles with an attractive interaction. 4> in is the depth of the attractive minimum of the interaction potential, and p is the particle density (averaged of the syston volume). Only the states above ihtfull line, the bimodal, are stable. The states between the full and the dashed lines, the spinodal, are metastable, and the states below the spinodal are linearly unstable. The system considered in Archer and Evans [7] is quenched from a stable slate circle) into the unstable region as indicated by the vertical arrow...
