collective motion

collective motion

[kə′lek·tiv ′mō·shən]
(nuclear physics)
Motion of nucleons in a nucleus correlated so that their overall space pattern is essentially constant or undergoes changes which are slow compared to the motions of individual nucleons.

In 1986, on the basis of a computer model, Jurgen Bosse of the Freie Universitat Berlin and his colleagues predicted that a liquid consisting of two components -- one made up of lightweight particles and the other of heavy particles -- would have a special collective motion that travels through the mixture like a sound wave but at a speed several times faster than that of ordinary sound in the mixture.
The collective motion of the buildings vibrated sediments filling the Los Angeles basin, sending long-period waves speeding toward Pasadena.
Other popular theories call for some kind of electronic motions, such as collective motion or local polarization of electrons, to mediate the exchange process.
When light is beamed onto the test strip's surface, the silver's electrons undergo a collective motion known as a surface plasmon.
Objective: The motion of artificial microswimmers can strikingly resemble collective motion in biological systems even though it only involves physical and chemical processes.
Take for instance the proteins in your muscles: At each contraction stimulated by the brain, an uncountable number of proteins change their structures to create the collective motion of the contraction.
In order to create enhanced spin currents, the researchers used the collective motion of spins called spin waves (the wave property of spins).
tracks this collective motion -- dubbed the "dark flow" -- to twice the distance originally reported.
Contributors from computer science and other technical fields and from medical and biological sciences consider such topics are methods and experiences of monitoring pedestrian behavior, classifying collective motion, the praxis of cognitive assistance in smart homes, learning about preferences and common behavior of the user in an intelligent environment, and ambient spatial intelligence.
It seems to me, that the analogous behavior of liquids in these states finds its explanation in the correspondence of the collective motion of the molecules, which one names the similarity of motions.
Similarly, in dielectrics or semiconductors, the laser-driven collective motion of electrons can occur on this characteristic time scale.
