Driven and Self-Driven Transport in Model Active Systems

Explore the transport phenomena in driven and self-driven soft matter systems through this insightful conference talk. Delve into the distinctions between globally driven systems with external forcing and locally driven 'active' systems with energy injected at the particle level. Examine simple particle models, including spinning particles driven by rotating external fields and isotropic self-propelled particles powered by internal energy depots. Discover how the interaction between particle dynamics and driving forces leads to collective transport at larger scales. Investigate the hybrid scenario of combined local and global driving, focusing on the shear rheology of dense self-propelled particle systems from liquid to glassy states. Gain valuable insights into the crucial role of activity in determining the flow properties of dense materials, with particular emphasis on the yield stress surface in the activity-density-shear parameter space.
