Defect dynamics in active smectics induced by confining geometry and topology

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