Topological Disorder in Spin Models on Hierarchical Lattices
N. S. Ananikian, K. G. Sargsyan
A general approach for the description of spin systems on hierarchial lattices with coordination number as a dynamical variable is proposed. The ferromagnetic Ising model on th…

Thermodynamic chaos and infinitely many critical exponents in the Baxter-Wu model
S. K. Dallakyan, N. S. Ananikian, R. G. Ghulghazaryan
The mechanisms leading to thermodynamic chaos in the Baxter-Wu model is considered. We compare the Baxter-Wu model with triangular antiferromagnets and discuss the difficulties rel…

The Chaotic Properties of the Q-state Potts Model on the Bethe Lattice:Q<2
N. S. Ananikian, S. K. Dallakian, B. Hu
The Q- state Potts model on the Bethe lattice is investigated for Q<2. The magnetization of this model exhibits a complicated behavior including both the period doubling bifurcatio…
