Title Dynamics and Rheology of Glassy Active Matter
 
Abstract: 
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 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.
