Abstract
An antiferromagnetic version of the well-known majority voter model on square
and honeycomb lattices is proposed. Monte Carlo simulations give evidence for a
continuous order-disorder phase transition in the stationary state in both
cases. Precise estimates of the critical point are found from the combination
of three cumulants, and our results are in good agreement with the reported
values of the equivalent ferromagnetic systems. The critical exponents \$1/\nu\$,
\$\gamma/\nu\$ and \$\beta/\nu\$ were found. Their values indicate that the
stationary state of the antiferromagnetic majority voter model belongs to the
Ising model universality class.
