Collective dynamics of chemotactic cells

Charlie Duclut

Abstract: Understanding the self-organization of living systems is one of the biggest conceptual challenges of the present century. A generic mechanism that drives such organization is interaction among the individual elements — which may represent cells, bacteria, or even enzymes — via chemical signals. After deriving a minimal microscopic model for a single chemotactic particle, I will present a coarse-grained model to describe an assembly of such particles. I will then study the scaling properties of this model using a dynamical renormalization group approach. This analysis reveals exact dynamic scaling exponents that represent superdiffusive behavior of the particles. The number fluctuations within sub-regions of the system show either a hyperuniform structure or exhibit giant number fluctuations, depending on whether or not the noise is conserved.
