Activity-Induced Interactions and Collective Response in Model Active Matter

Explore a comprehensive seminar presentation by Professor Ignacio Pagonabarraga from Universitat de Barcelona examining the fascinating world of active matter systems and their collective behaviors. Delve into the study of coordinated motion in living systems like bird flocks, fish schools, and bacterial colonies, where energy-consuming elements exchange information and respond to chemical signals. Learn about artificial systems like nanorobots and their movement mechanisms through heterogeneous chemical processes. Understand the fundamental out-of-equilibrium nature of these systems, their long-range spatial correlations, and slow relaxation times. Discover how statistical models reveal the importance of shape and symmetries in non-equilibrium phase transitions, the response to localized perturbations, and the implications for effective interactions in active suspensions. Gain insights into the basic principles governing emergence and self-assembly in active systems through this hour-long presentation delivered as part of the New Statistical Physics in Living Matter series at the Isaac Newton Institute.
