What does “self” in self-organisation refer to? Is there a physical process mediating this “self”-organisation? In this talk I will explain how these questions can be similarly addressed for diverse system classes which are based on interactions that conserve some quantity, such as mass in chemical dynamics, strategies in zero-sum games, or prices in transactions on liquid markets. I will start from the observation that lateral instabilities in reaction-diffusion systems generically induce movement of local equilibria. Using a well-established model for biological pattern formation as a paradigmatic example, I will show that such shifts can destabilise local equilibria endogenously, driving the system into a turbulent state. Remarkably, this shows that order can re-emerge from the turbulent state when distinct unstable modes work in concert to control local destabilisation.
