Coarsening and persistence in the voter model
Coarsening and persistence in the voter model
The voter model is a simple model for coarsening with a nonconserved scalar order parameter. We investigate coarsening and persistence in the voter model by introducing the quantity ${\mathit{P}}_{\mathit{n}}$(t), defined as the fraction of voters who changed their opinion n times up to time t. We show that ${\mathit{P}}_{\mathit{n}}$(t) exhibits …
