Random-current phase transition conjecture on the hexagonal lattice
Random-current phase transition conjecture on the hexagonal lattice
Let be the hexagonal lattice. Denote by the single random-current measure and by the associated random-cluster model.
Hexagonal-lattice random-current conjecture. All phase transitions of the random current and random-cluster model on the hexagonal lattice coincide:
The loop model has an explicitly understood phase diagram on the hexagonal lattice, whereas the random-current measure is expected to exhibit a more generic behaviour. The conjectured equality remains open in the source.
