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.

Optimal diffusive search: nonequilibrium resetting versus equilibrium dynamics (2012, background): “Coli bacteria alternates ballistic moves (or ‘runs’) with random changes of direction (‘tumbles’) in order to reach regions with high concentration of a chemo-attractant (chemotactic search) [7, 8, 9].”
Pressure is not a state function for generic active fluids (2014, background): “2, the flux-free steady state has ρ ∝ 1/v throughout [25, 26, 35], so that the pressures P1,2 ∝ ρv2 are unequal.”
Irreversibility in Active Matter Systems: Fluctuation Theorem and Mutual Information (2018, background): “[25] J.”
Active Particles in Complex and Crowded Environments (2016, methodology): “This was first predicted theoretically (Fily and Marchetti, 2012; Redner et al., 2013a; Tailleur and Cates, 2008) and has recently been observed experimentally (Buttinoni et al., 2013; Palacci et al., 2013).”
Intermittent search strategies (2011, background): “We can quote the very classical example of chemotaxis (Berg, 2004), which keeps arising interest in the biological and physical communities (see for example Kafri and Da Silveira (2008); Tailleur and Cates (2008); Yuzbasyan et al. (2003)).”
Hydrodynamics of soft active matter (2013, background): “Recent work also revealed mechanisms that can yield true phase separation (hence large number fluctuations) in active systems in the absence of an ordered state (Tailleur and Cates, 2008; Cates, 2012; Fily, Baskaran, and Marchetti, 2012).”
Classical dynamical density functional theory: from fundamentals to applications (2020, background): “Moreover, Dean’s results are of importance in active matter physics [248–255].”
Entropy production in field theories without time reversal symmetry: Quantifying the non-equilibrium character of active matter (2016, background): “It captures in stylized form the coarse-grained many-body dynamics of active particles with either discrete [10, 21] or continuous [54, 55] angular relaxation of their self-propulsion direction.”
Cluster Phases and Bubbly Phase Separation in Active Fluids: Reversal of the Ostwald Process (2018, background): “In summary, our explicit coarse graining shows that both of the TRS-breaking terms considered in AMB+ (5,6) emerge naturally from at least one well-motivated model for the microscopic dynamics of interacting active particles.”
The statistical physics of active matter: From self-catalytic colloids to living cells (2017, background): “Amicroscopic phenomenological picture has emerged to describeMIPS.”
Physics of microswimmers—single particle motion and collective behavior: a review (2014, background): “…to achieve a theoretical understanding of the generic principles underneath the propulsion-induced phase transitions (Bialké et al., 2013; Cates and Tailleur, 2013; Fily et al., 2014b; Fily and Marchetti, 2012; Stenhammar et al., 2014, 2013; Tailleur and Cates, 2008; Wittkowski et al., 2014).”
