Active matter and active materials: emerging behavior in intrinsically out of equilibrium systems

Professor Ignacio Pagonabarraga

CECAM, Ecóle Polytechnique Fédérale de Lausanne (EPFL), Lausanne, Switzerland 

Thursday 11th May 2017
Time: 4pm
Venue: Lecture Room G20, Royal School of Mines, Imperial College London, South Kensington Campus
Contact: Arash Mostofi

Flocks of birds, schools of fishes, or bacterial colonies constitute examples of living systems that coordinate their motion. In all these systems their constituent elements generate motion due to energy consumption and can exchange information or react sensitively to chemical cues in order to move together or to react collectively to external signals. Artificial systems, such as nanorobots, exploit the heterogeneous compositions of their surface to displace  as a result of the heterogeneous chemical reactions. In this talk I will  introduce simple statistical   models to analyze the implications that self-propulsion has in the emergence of self-assembled structures in suspensions of model self-propelled particles. I will compare different types of active systems  to discern between specific ingredients and general features determining the emergent properties of active matter

I will also briefly introduce CECAM (Centre Européen de Calcul Atomique et Moléculaire), an European institution devoted to promote cooperation and foster fundamental research amongst the scientific communities dedicated to computationally intensive methods and grand challenges. I will describe what has CECAM accomplished, the opportunities it offers, and the challenges ahead.
