Figure 3: First row: snapshots of equilibrium configurations obtained by Monte Carlo simulations as described in Section 2.2. Second row: ground state shapes calculated with the minimization process as described in Section 2. Pressure differences are in units . All the shapes were calculated for . Parameters for first row pictures are as follows: (a) (with ), (b) (with ), (c) (with ), and (d) (with ). Shapes in the second row were calculated for the following reduced volumes: (a) , (b) , (c) , and (d) .
