DESCRIPTION:Speaker: Nir Gov\nhosted by Edouard Hannezo\nAbstract: Anyone w
 ho has moved furniture together with friends will appreciate that cooperat
 ive transport requires some non-trivial communication. Yet ants are adept 
 at collectively moving objects several times their size. How they do so ha
 s long been a subject of research\, but recent advances have suggested tha
 t this communication occurs through the forces the ants exert on the load.
  This implies that the collective transport problem can be mapped to an Is
 ing model\, in which decisions by individual ants are described by spin fl
 ips. Within this framework\, the group is poised in the vicinity of the tr
 ansition between uncoordinated and coordinated motion. It thus profits fro
 m both internal coordination and maximal responsiveness to external inform
 ation\, mediated by temporarily informed leader ants. Here\, we review the
  implications of these findings for cooperative transport\, and discuss th
 e way in which a more complete multiscale understanding of such systems wo
 uld require the development of a new formalism that combines statistical p
 hysics of interacting particles with the cognitive capabilities of individ
 uals.
