Electrons whizzing around each other and humans crammed together at a political rally don't seem to have much in common, but researchers at Cornell are connecting the dots.

They've developed a highly accurate mathematical approach to predict the behavior of crowds of living creatures, using Nobel Prize-winning methods originally developed to study large collections of quantum mechanically interacting electrons. The implications for the study of human behavior are profound, according to the researchers.

For example, by using publicly available video data of crowds in public spaces, their approach could predict how people would distribute themselves under extreme crowding. By measuring density fluctuations using a smartphone app, the approach could describe the current behavioral state or mood of a crowd, providing an early warning system for crowds shifting toward dangerous behavior.

Tomas Arias, professor of physics, is lead author of "Density-Functional Fluctuation Theory of Crowds," which published Aug. 30 in Nature Communications.
