Abstract

We use a sharp interface model for active cells to study the jamming transition point and behavior near it by varying cell concentration, active velocity and elasticity, including a binary mixture of soft and stiff cells. We determine the jamming transition point, as well as behavior near the transition,including the effective diffusion, and sixfold bond correlations. Finally, we expand on previous studies by showing the Voronoi dimensionless cell shape can be treated as an order parameter at any concentration.
