Correlation Length and Average Loop Length of the Fully-Packed Loop Model
Abstract
The fully-packed loop model of closed paths covering the honeycomb lattice is studied through its identification with the slq(3) integrable lattice model. Some known results from the Bethe ansatz solution of this model are reviewed. The free energy, correlation length, and the ensemble average loop length are given explicitly for the many-loop phase. The results are compared with the known result for the model's surface tension. A perturbative formalism is introduced and used to verify results.
