Phys. Rev. Lett. 100, 218103 (2008) [4 pages]Statistical Mechanics of Interacting Run-and-Tumble BacteriaReceived 7 March 2008; published 29 May 2008 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. © 2008 The American Physical Society URL:
