{"abstract":[{"lang":"eng","text":"Spontaneous formation of colonies of bacteria or flocks of birds are examples of self-organization in active living matter. Here, we demonstrate a form of self-organization from nonequilibrium driving forces in a suspension of synthetic photoactivated colloidal particles. They lead to two-dimensional \"living crystals,\" which form, break, explode, and re-form elsewhere. The dynamic assembly results from a competition between self-propulsion of particles and an attractive interaction induced respectively by osmotic and phoretic effects and activated by light. We measured a transition from normal to giant-number fluctuations. Our experiments are quantitatively described by simple numerical simulations. We show that the existence of the living crystals is intrinsically related to the out-of-equilibrium collisions of the self-propelled particles."}],"year":"2013","day":"22","language":[{"iso":"eng"}],"author":[{"full_name":"Palacci, Jérémie A","id":"8fb92548-2b22-11eb-b7c1-a3f0d08d7c7d","first_name":"Jérémie A","orcid":"0000-0002-7253-9465","last_name":"Palacci"},{"full_name":"Sacanna, S.","first_name":"S.","last_name":"Sacanna"},{"full_name":"Steinberg, A.
