Symmetry and stability of orientationally ordered collective motions of self-propelled, semiflexible filaments by Madhuvanthi Guruprasad Athani, Daniel A. Beller

“…Ordered, collective motions commonly arise spontaneously in systems of many interacting, active units, ranging from cellular tissues and bacterial colonies to self-propelled colloids and animal flocks. Active phases are especially rich when the active units are sufficiently anisotropic to produce liquid crystalline order and thus active nematic phenomena, with important biophysical examples provided by cytoskeletal filaments including microtubules and actin. …”
