Dynamics and Rheology of Glassy Active Matter

Rituparno Mandal

Georg-August-Universität Göttingen

Two major outstanding questions in theoretical physics are how to describe (a) driven or active systems far from equilibrium and (b) disordered systems characterized by a very slow relaxation (e.g. glassy dynamics). In this presentation, I will attempt to provide a unified theoretical and computational description of an active glass, a system that exists at the intersection of these two challenging domains. Examples include epithelial tissue, the cellular cytoplasm, a dense assembly of self-propelled colloids, to name a few. I would like to discuss the dynamics and phase diagram of a canonical model of active glassy matter and show how the rheological perturbation in such a system can lead to a novel type of shear induced ordering. I will also provide an outlook on pertinent questions and discuss briefly about the possible future directions.
