Self-assembled magnetic swimmers and magnetic mixing in driven magnetic suspensions at a liquid-air interface
Ensembles of interacting particles subject to a periodic external forcing often develop a nontrivial collective dynamic response. A collective behavior in such systems is determined by parameters of external excitations as well interactions...
