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.

Trapping of a run-and-tumble particle in an inhomogeneous domain: the weak noise limit
Asymptotic methods are used to calculate the mean first passage time (MFPT) for a one-dimensional RTP to escape an effective trapping potential generated by space-dependent switching rates.
Run-and-tumble particles in speckle fields.
The static and dynamic properties of an active suspension of swimming bacteria embedded into speckle patterns are investigated by means of molecular dynamics simulations to observe a crossover phenomenon when the forces exerted by the speckles are equal to the bacteria's propulsion.
Effective run-and-tumble dynamics of bacteria baths.
It is shown that it is possible to reproduce the dynamics of density fluctuations in the system using a free run-and-tumble model with effective fitting parameters and the dependence of these parameters, e.g., the tumbling rate, tumbling time and self-propulsion velocity, on the density of the bath.
Lattice models of nonequilibrium bacterial dynamics
This lattice model constitutes an efficient tool to simulate a class of interacting run-and-tumble models relevant to bacterial motion, so long as certain conditions are met.
Pattern formation in self-propelled particles with density-dependent motility.
It is shown that interactions lead generically to the formation of a host of patterns, including moving clumps, active lanes, and asters, which could explain many of the patterns seen in recent experiments and simulations.
Run-and-tumble motion in one dimension with space-dependent speed.
We consider a particle performing run-and-tumble dynamics with space-dependent speed. The model has biological relevance as it describes motile bacteria or cells in heterogeneous environments. We
Spontaneous segregation of self-propelled particles with different motilities
We study mixtures of self-propelled and passive rod-like particles in two dimensions using Brownian dynamics simulations. The simulations demonstrate that the two species spontaneously segregate to
First-passage time of run-and-tumble particles
The problem of first-passage time for run-and-tumble particles in one dimension is solved, considering external force fields and chemotactic fields, giving rise to space-dependent swim speed and tumble rate.
Kuramoto model with run-and-tumble dynamics.
This work considers an extension of the Kuramoto model with run-and-tumble dynamics-a type of self-propelled motion that undergoes phase transition and offers a simple case study for investigating phase transition for a system with self- Propelled particles.
Run-and-tumble motion in a harmonic potential: field theory and entropy production
Run-and-tumble (RnT) motion is an example of active motility where particles move at constant speed and change direction at random times. In this work we study RnT motion with diffusion in a harmonic


Collective Motion of Self-Propelled Particles: Kinetic Phase Transition in One Dimension
We demonstrate that a system of self-propelled particles exhibits spontaneous symmetry breaking and self-organization in one dimension, in contrast with previous analytical predictions. To explain
Dynamics of interacting particle systems: stochastic process and field theory
We present an approach to the dynamics of interacting particle systems, which allows us to derive path integral formulae from purely stochastic considerations. We show that the resulting field theory
Concentration dependence of the collective dynamics of swimming bacteria.
The concentration dependence of correlations in the collective state is probed with a novel technique that herds bacteria into condensed populations of adjustable concentration, and for the particular thin-film geometry employed the correlation lengths vary smoothly and monotonically through the transition from individual to collective behavior.
Onset of collective and cohesive motion.
It is found that this phase transition, in two space dimensions, is always discontinuous, including for the minimal model of Vicsek et al. for which a nontrivial critical point was previously advocated.
Self-concentration and large-scale coherence in bacterial dynamics.
It is found in sessile drops that flows related to those in the Boycott effect of sedimentation carry bioconvective plumes down the slanted meniscus and concentrate cells at the drop edge, while in pendant drops such self-concentration occurs at the bottom.

The general theory of random walks in continuum is formulated, essential for treating a collision rate which depends smoothly upon direction of motion, and a smooth probability distribution of correlations between the directions of motion before and after collisions is considered.
Coherent structures in monolayers of swimming particles.
The simulation results clearly illustrate that coherent structures, such as aggregation, mesoscale spatiotemporal motion, and band formation, can be generated by purely hydrodynamic interactions.
Steady-State Chemotactic Response in E. coli
This work relates this stochastic behavior of E. coli to the steady-state density of a bacterium population, and derives the latter as a function of chemoattractant concentration.
