Phase coexistence in Ising, Potts and percolation models
Phase coexistence in Ising, Potts and percolation models
We study phase coexistence (separation) phenomena in Ising, Potts and random cluster models in dimensions d⩾3 below the critical temperature. The simultaneous occurrence of several phases is typical for systems with appropriately arranged (mixed) boundary conditions or for systems satisfying certain physically natural constraints (canonical ensembles). The various phases emerging …
