Defect dynamics in active smectics induced by confining geometry and topology

It is intriguing but challenging to control the complex dynamics of topological defects BODY BALM that emerge in nonequilibrium spatiotemporal systems.Through an effective modelling this work explores a 332 viable way to controllably vary the properties of persistent defect dynamics in self-propelled active smectics via the competition of activity and boundary confinements with different topology and geometry.
