Phys. Rev. E 69, 026603 (2004) [6 pages]Energy funneling in a bent chain of Morse oscillators with long-range couplingReceived 13 October 2003; published 17 February 2004 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. © 2004 The American Physical Society URL:
