- Descrição
- Within a real-space renormalization group (RG) framework, we study the criticality of the Z(4) ferromagnet on square lattice. The phase diagram (exhibiting ferromagnetic, paramagnetic and nematic like phases) recovers ''all'' the available ''exact'' results, and possibly is a high precision one everywhere. In particular we establish the main asymptotic behaviors (bifurcation and Ising regions). In addition to that, we develop an operational procedure (Break-collapse method) which considerably simplifies the ''exact'' calculation of arbitrary Z(4) two- terminal clusters (commonly appearing in RG approaches).
