- Descripción
- Within a real space renormalisation group approach, we study the phase diagram and the universality classes of the three-state chiral clock model in a self-dual planar hierarchical lattice. We find that the chiral field <math>\Delta </math> is relevant at the pure Potts critical point with a crossover exponent <math>\simeq </math> 0.32. The critical line which separates the ferromagnetic phase from the non-ferromagnetic ones is characterized by a multicritical (Lifshitz) point located at (K, <math>\Delta </math>) <math>\simeq </math> (1.452,0.382). The ferromagnetic phase appears to be divided into two regions by a wetting line which we also locate numerically. The various critical lines. and point of the phase diagram are believed to be excellent approximations for the square lattice.
