In the active Ising model, increasing alignment strength pins interfaces between traveling domains via resonating particle motion, causing macroscopic pinned regions that suppress polar order when diffusion is much slower than self-propulsion.
The occupation numbers at sites along the domain boundary are required to be larger than a cutoff valueρcutoff = 5ρ0

Motility-Induced Pinning in Flocking System with Discrete Symmetry
In the active Ising model, increasing alignment strength pins interfaces between traveling domains via resonating particle motion, causing macroscopic pinned regions that suppress polar order when diffusion is much slower than self-propulsion.
