Energy funneling in a bent chain of Morse oscillators with long-range coupling
arXiv:nlin/0310023 · doi:10.1103/PhysRevE.69.026603
Abstract
A bent chain of coupled Morse oscillators with long-range dispersive interaction is considered. Moving localized excitations may be trapped in the bending region. Thus chain geometry acts like an impurity. An energy funneling effect is observed in the case of random initial conditions.
