Dynamics of the force exchanged between membrane inclusions.
We study the dynamical response of a fluid membrane to the sudden conformation change of active inclusions linearly coupled to the membrane curvature. The mutual force between two inclusions triggered simultaneously is shown to exhibit a transient maximum much larger than the equilibrium force. Even in the presence of tension, this dynamical interaction is long range over distances much larger than the correlation length. We derive the scaling laws describing these phenomena analytically, and we stress the importance of the damping due to intermonolayer friction.
