Six–vertex model with domain wall boundary conditions in the Bethe–Peierls approximation
Leticia F. Cugliandolo, Giuseppe Gonnella, Alessandro Pelizzola
We use the Bethe-Peierls method combined with the belief propagation algorithm to study the arctic curves in the six vertex model on a square lattice with domain-wall boundary conditions, and the six vertex model on a rectangular lattice with partial domain-wall boundary conditions. We show that this rather simple approximation yields results that are remarkably close to the exact ones when these are known, and allows one to estimate the location of the phase boundaries with relative little effort in cases in which exact results are not available.
