Additional Long-Range Interactions on Diamond-Type Hierarchical Lattices
Song Li, Zhao‐Di Yang · Communications in Theoretical Physics · 1996
The Ising model with additional next-nearest neighbour (n.n.n.) interactions in generator of diamond-type hierarchical lattice is studied. It is found that phase transition occurs only when the nearest neighbour (n.n.) interaction and n.n.n. interaction fulfils a certain relation and the universal class of phase transition is not changed by the long-range interactions.
