It has been numerically found that the setup of Newton’s cradle can exhibit a rigid-body like behavior, that is, the target cluster starts to move collectively without emitting the outermost particle if the purely repulsive interaction between the neighbouring particles is very “soft” (Phys. Rev. Lett. 104:124302, 2010). We show theoretically that such an interaction leads to an evanescent mode within the cluster, which delivers the momentum within the cluster without any propagating oscillation.
