Spin-3/2 Ising Model and Ashkin-Teller Model

Tomoya Horiguchi, Yasushi Honda

Open publisher page 17 citations

Abstract

We derive a relation between a general spin-3/2 Ising model and an Ising model with two sets of Ising spins. A spin-3/2 Ising model with up-down symmetry is expressed in terms of an Ashkin-Teller model and solved exactly in some cases without assuming extended Horiguchi's condition. It turns out that the system on the square lattice shows rich critical phenomena.
