Noise induced phase transition in the -state block voter model
J. M. de Araújo, C. I. N. Sampaio Filho, F. G. B. Moreira
We use Monte Carlo simulations and finite-size scaling theory to investigate the phase transition and critical behavior of the -state block voter model on square lattices. It is…
