摘要

On Archimedean lattices, the Ising model exhibits spontaneous ordering. Three examples of these lattices of the majority-vote model with noise are considered and studied through extensive Monte Carlo simulations. The order/disorder phase transition is observed in this system. The calculated values of the critical noise parameter are qc=0.089(5), qc=0.078(3), and qc=0.114(2) for honeycomb, Kagom and triangular lattices, respectively. The critical exponents [beta]/[nu], [gamma]/[nu] and 1/[nu] for this model are 0.15(5), 1.64(5), and 0.87(5); 0.14(3), 1.64(3), and 0.86(6); 0.12(4), 1.59(5), and 1.08(6) for honeycomb, Kagom and triangular lattices, respectively. These results differ from the usual Ising model results and the majority-vote model on so-far studied regular lattices or complex networks. The effective dimensionalities of the system (honeycomb), (Kagom), and (triangular) for these networks are just compatible to the embedding dimension two.
