Glassy Dynamics and Jamming in Dense Persistent Active Matter

Explore a detailed seminar presentation by Professor Chandan Dasgupta from the Indian Institute of Science examining the effects of activity on glassy dynamics and jamming in dense persistent active matter systems. Delve into the theoretical understanding of non-equilibrium phenomena in biological systems like bacterial cytoplasm, cytoskeleton-motor complexes, and epithelial cell sheets through molecular dynamics and Brownian dynamics simulations. Learn how active forces and persistence time influence glass transition, with short persistence times showing behavior similar to typical glass transitions while reducing transition temperature and kinetic fragility. Discover the unique characteristics of systems with large persistence times, including intermittency patterns and plastic yielding, and examine the properties of homogeneous liquid states with infinite persistence time. Understand the three-stage relaxation process of jamming, the relationship between system size and correlation length, and how properties of jammed states with small active forces differ from passive jammed systems. The presentation, part of the New Statistical Physics in Living Matter series, provides comprehensive insights into the complex dynamics of active matter systems.
