Query: Elastic Cheerios effect: self-assembly of cylinders on a soft solid   A rigid cylinder placed on a soft gel deforms its surface. When multiple
cylinders are placed on the surface, they interact with each other via the
topography of the deformed gel which serves as an energy landscape; as they
move, the landscape changes which in turn changes their interaction. We use a
combination of experiments, simple scaling estimates and numerical simulations
to study the self-assembly of cylinders in this elastic analog of the Cheerios
effect for capillary interactions on a fluid interface. Our results show that
the effective two body interaction can be well described by an exponential
attraction potential as a result of which the dynamics also show an exponential
behavior with respect to the separation distance. When many cylinders are
placed on the gel, the cylinders cluster together if they are not too far
apart; otherwise their motion gets elastically arrested.
