Continuous majority-vote model.

We introduce a kinetic irreversible XY model and investigate its dynamic critical behavior through short-time Monte Carlo simulations on square lattices with periodic boundary conditions, starting from an ordered state. We find evidence that this system exhibits a Kosterlitz-Thouless-like phase for low values of the noise parameter. We present results for the correlation function exponent eta for several noise values. We also find that the dynamic critical exponent z is in agreement with the value expected for local update Monte Carlo rules.
