Exact solution of a Z(4) gauge Potts model on planar lattices
N. S. Ananikian, R. G. Ghulghazaryan, N. Sh. Izmailian +1
The exact solution of a general Z(4) gauge Potts model with a single and double plaquette representation of the action is found on a subspace of gauge-coupling parameters on the sq…
Correlation Functions of Multisite Interaction Spin-S models on the Bethe-like Lattices
R. G. Ghulghazaryan
Multisite interaction spin-S models in an external magnetic field are studied recursively on the Bethe-like lattices. The transfer-matrix method is extended to calculate exactly 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…
