Hydrodynamics and phases of flocks

J Toner, Y Tu, S Ramaswamy - Annals of Physics, 2005 - Elsevier
We review the past decade's theoretical and experimental studies of flocking: the collective,
coherent motion of large numbers of self-propelled “particles”(usually, but not always, living …

111 years of Brownian motion

X Bian, C Kim, GE Karniadakis - Soft Matter, 2016 - pubs.rsc.org
We consider the Brownian motion of a particle and present a tutorial review over the last 111
years since Einstein's paper in 1905. We describe Einstein's model, Langevin's model and …
