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.
我们考虑一维空间中经历“奔跑-翻滚”动力学（如大肠杆菌所表现的）的自推进粒子。基于先前在单粒子密度的漂移扩散层面的分析，我们加入了相互作用和噪声，从而能够讨论通过“自捕获”形成的区域以及其他集体现象。在某些情况下，可以映射到细致平衡系统。
