Coarsening of topological defects in 2D polar active matter
We numerically study the coarsening of topological defects in 2D polar active
matter and make several interesting observations and predictions. (i) The long
time state is characterized by nonzero density of defects, in stark contrast to
theoretical expectations. (ii) The kinetics of defect coarsening shows power
law decay to steady state, as opposed to exponential decay in thermal
equilibrium. (iii) Observations (i) and (ii) together suggest emergent
screening of topological charges due to activity. (iv) Nontrivial defect
coarsening in the active model leads to nontrivial steady state patterns. We
investigate, characterize, and validate these patterns and discuss their
biological significance.Comment: Movies are available in the ancillary folde
