摘要: Transverse Ising models with arbitrary spin S are studied by use of the pair approximation discretized path-integral representation. The equation for phase diagram is derived an number nearest-neighbour spins z and critical lines obtained numerically a few values spin. It easy to show that in limit infinity results infinite-range interaction model can be within present formulation.
