| Description | Have shown that extended ensemble calculations can be used to find very small energy differences between phases. Have shown that the free energy difference between the columnar and cubatic phase of hard cut spheres of aspect ratio 0.2 is very small over a range of densities. This limits the potential stability of the cubatic phase for this system, and hence suggests it will be very hard to find this phase in colloidal systems. Have shown that moving from a circular to a square cross-section for colloidal particles, leads to a stabilization of the cubatic phase. Hence, we expect it to be found experimentally in systems of colloidal particles in the future. |
