Statistical mechanics of interacting run-and-tumble bacteria

Research output: Contribution to journalArticlepeer-review


We consider self-propelled particles undergoing run-and-tumble dynamics ( as exhibited by E. coli) in one dimension. Building on previous analyses at drift-diffusion level for the one-particle density, we add both interactions and noise, enabling discussion of domain formation by "self-trapping,'' and other collective phenomena. Mapping onto detailed-balance systems is possible in certain cases.
