Active many-particle systems and the emergent behavior of dense ant collectives

Abstract

Abstract This article discusses recent work with fire ants, Solenopisis invicta, to illustrate the use of the framework of active matter as a base to rationalize their complex collective behavior. We review much of the work that physicists have done on the group dynamics of these ants, and compare their behavior to two minimal models of active matter, and to the behavior of the synthetic systems that have served to test and drive these models.
