Geometry, defects and motion in active matter

12.03.2020 10:30 – 11:30

The paradigm of “active matter” has had notable successes over the past decade in describing self-organization in a surprisingly broad class of biological and bioinspired systems: from flocks of starlings, down to bacterial colonies and the cell cytoskeleton. Active systems are generic nonequilibrium assemblies of anisotropic components that are able to convert stored or ambient energy into motion. In this talk I will discuss some recent theoretical and experimental work on active fluids confined on two-dimensional curved interfaces and highlight how the geometrical and topological structure of the environment can substantially affect collective motion in active materials, leading to spectacular life-like functionalities.
