The Ising Model on the Cactus Tree
Takashi Tsuchiya · Progress of Theoretical Physics · 1976
The Ising model on the cactus tree which is constructed by the introduction of smallest possible loops into the Cayley tree is studied. The nearest-neighbor interactions are not restricted to ferromagnetism but taken as general as possible. Physical quantities which are influenced by the existence of the loops and the antiferromagnetic interactions are reported.
