Synchronization of cilia — •Benjamin M. Friedrich — cfaed, TU Dresden, Dresden, Germany

I will present a historical overview on synchronization of cilia and flagella, featuring key experiments in the field. Two mechanisms, (i) synchronization by direct hydrodynamic interactions and by (ii) mechanical self-stabilization in self-propelled swimmers will be addressed. I will review the minimal model of rotating spheres of Vilfan and Jülicher, which has been influential in the field. This model highlights how synchronization depends on broken parity-time symmetry. Recently, this theoretical model has been realized experimentally using colloidal particles driven by optical tweezers.
