Title: Dynamics and Rheology of Glassy Active Matter

Date and Time: 20th January 2023 (Friday) at 02:30 PM (Coffee/Tea: 02:15 PM)

Venue: Nevill Mott Hall

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 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, and a dense assembly of self-propelled colloids, to name a few. I will discuss the dynamics and phase diagram of a canonical model of active glassy matter and show how 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 the possible future directions.
