Meso-scale turbulence in living fluids (2012, methodology): “Histograms and structure functions for quasi-2D (3D) curves were obtained by combining PIV data from two (15) movies, respectively, representing an average over 2 × 1;000 (15 × 300) frames.”
Collective motion and density fluctuations in bacterial colonies (2010, background): “Systems of apolar (bidirectionally moving) particles also exhibit anomalous density fluctuations but with a scaling exponent closer to 1, as found in theory (16), numerics (12), and experiments (7, 38).”
Active Particles in Complex and Crowded Environments (2016, background): “It has in fact become a challenge for theoretical physics to find minimal statistical models that capture these features (Bertin et al., 2009; Li et al., 2008; Toner et al., 2005).”

Colloquium: Criticality and dynamical scaling in living systems (2017, background): “…(1995) which models collective motion by assuming that an individual in a group essentially follows the trajectory of its neighbors, with some deviations treated as noise,40 and (ii) continuum (hydrodynamic) theories, more amenable to theoretical analysis (Toner and Tu, 1995; Toner et al., 2005).”
Brownian motion of a self-propelled particle. (2010, background): “There are numerous realizations of self-propelled particles [1, 2] in nature ranging from bacteria [3–10] and spermatozoa [11–14] to artificial colloidal microswimmers.”

Temperature in and out of equilibrium: A review of concepts, tools and attempts (2017, background): “Two major ordering modes in active systems – which can also combine together – are phase separation [297] and swarming [298,299]: the former is typically a dilute–dense transition (often simply called clustering, or in the most extreme cases, jamming and crystallization), the latter consists in a ma”
Topological sound in active-liquid metamaterials (2016, methodology): “The analog of Navier-Stokes equations that describe a one-component fluid of self-propelled particles (with overdamped particle dynamics, see Supplementary Information [SI]) are the Toner-Tu equations [6, 8, 23], which in their simplest form read:”
