Bavaud, François Isoperimetric phase transitions of two-dimensional droplets. (English) Zbl 0715.58054 Commun. Math. Phys. 132, No. 3, 549-554 (1990). Summary: We consider two-dimensional assemblies of particles governed by hamiltonians depending on the area and the perimeter of their convex hull. Provided the hamiltonian is quadratically homogeneous in the coordinates, we find an exact formula for the free energy. Phase transitions resulting from the competition between area and perimeter can easily be produced and explicitly dealt with. We illustrate those features by a simple example undergoing a second-order transition.
