Simulations of Active Nematics

Simulations of a model for microtubule(MT)-based active nematics capture experimentally observed defect dynamics. The image on the right shows three sequential images from experimental system in which +½ and -½ defects are created through a bending stability and subsequently separate. The image on the left shows similar defect behaviors observed in dynamical simulations of a coarse grain model for the MTbased active nematics.
