At Auditorium BARB 11

Abstract :
Reactive systems maintained far from equilibrium are known to generate various types of spatiotemporal organizations. These structures are often macroscopic and involve time scales that are much longer than the typical reaction times. The connection between the microscopic and macroscopic scales is commonly explained by the propagation of local correlations over large distances, which would be induced by non-reactive transport processes. In this talk, we will explore examples of real-life chemical systems to evaluate the plausibility of this mechanism. Data from atom microscope experiments and models of spatial coupling in living systems both suggest that nature often relies on more intricate ways to propagate chemical information.
