Majority-vote model with different agents
چکیده انگلیسی

We consider the majority-vote model with noise in a network of social interactions for a system with two classes of individuals, class σσ and class ττ. For the two-agent model each class has its own dynamics, with individuals of σσ class being influenced by neighbors of both classes, while the individuals of type ττ are influenced only by neighbors of that class. We use Monte Carlo simulations and finite-size scaling techniques to estimate the critical properties of the system in the stationary state. The calculated values of the critical noise parameters, qσ∗ and qτ∗, allow us to identify five distinct regions in the phase diagram on the qτ–qσqτ–qσ plane. The critical exponents for each class are the same and we conclude that the present model belongs to the same universality class as the two-dimensional Ising model.
