Description
Being groups of animals or populations of cells, active agents exhibit a fantastic richness of collective, or cooperative behaviour, responsible in many cases of providing function to biological or ecological systems. Can we develop predictive tools for these systems? Can we learn from them ways of fuctionalizing artificial materials? I'll address theses questions taking synthetic microswimmers as model systems, showing how one can tune their response to select different cooperative states. I'll also stress how the understanding of simplified theoretical models, can help in predicting the collective behaviour of mixtures of self-propelled (Janus) colloids with different self-propulsion speeds.
