- Descripción
- Within a real-space renormalisation group (RG) scheme, we study the criticality of the ferromagnetic Z(4) model on anisotropic square lattice. We use a RG cluster which has already proved to be very efficient for the Potts model on the same lattice. The establishment of the RG recurrence relations is greatly simplified through the break-collapse method. The phase diagram (exhibiting ferromagnetic, paramagnetic and nematic-like phases) recovers ''all'' the available ''exact'' results, and is believed to be a high precision one everywhere. If the model is alternatively thought as being associated with a particular hierarchical lattice rather than with the square one, then it is exact everywhere.
