SYAN: Symposium Active nematics: From 2D to 3D

SYAN 1: Active nematics: From 2D to 3D

Friday, October 1, 2021, 10:00–12:45, Audimax 1

Active nematics are one of the most studied manifestations of active matter with main examples being mixtures of cytoskeletal filaments and motor proteins, but also force-generating, deforming and reorienting cells in living tissue. While the vast majority of active nematics have been studied in 2D systems, recently several advances towards 3D active nematics were made. Examples are systems that undergo multiple transitions from 3D space-filling to a compressed sheet, active filaments embedded in a passive liquid crystal and organoids in the case of tissue. The symposium will feature the experimental and theoretical challenges in the transition from 2D to 3D active nematic systems and its implications.
