phase behavior19,20,21,22,23,24,25,26,27,28. For example, for regular hexagons24, a hexatic phase, a hexagonal rotator crystal, a hexagonal crystal, and a frustrated hexagonal crystal are found whereas for regular pentagons, whose fivefold rotational symmetry is not compatible with the symm...
this energy functional is reminiscent of the entropic chain stretching free energy of copolymeric self-assemblies in the strong segregation limit31. The Quantizer problem is the minimisation of the ‘total energy’, defined as the sum\(\mathop {\sum}\...
