摘要: Abstract A new type of cluster theory in Ising models is presented by the use differential operator technique and spin identity. In spin- 1 2 model, it gives same result as that Bethe–Peierls approximation, such for transition temperature. The formulation also applied to investigation phase diagrams both transverse model spin-1 system with a single-ion anisotropy.
