Dynamics of Vacillating Voters

Original · EN

We introduce the vacillating voter model in which each voter consults two neighbors to decide its state, and changes opinion if it disagrees with either neighbor. This irresolution leads to a global bias toward zero magnetization. In spatial dimension d>1, anti-coarsening arises in which the linear dimension L of minority domains grows as t¹/⁽ᵈ⁺¹⁾. One consequence is that the time to reach consensus scales exponentially with the number of voters.
