Self-sustained oscillations of active viscoelastic matter
Journal of Physics A: Mathematical and Theoretical IOP Publishing 55:27 (2022) 275601
Abstract:
Models of active nematics in biological systems normally require complexity arising from the hydrodynamics involved at the microscopic level as well as the viscoelastic nature of the system. Here we show that a minimal, space-independent, model based on the temporal alignment of active and polymeric particles provides an avenue to predict and study their coupled dynamics within the framework of dynamical systems. In particular, we examine, using analytical and numerical methods, how such a simple model can display self-sustained oscillations in an activity-driven viscoelastic shear flow.Activity gradients in two- and three-dimensional active nematics
