Standing wave instabilities in a chain of nonlinear coupled oscillators
Anna Maria Morgante, Magnus Johansson, Georgios Kopidakis +1
We consider existence and stability properties of nonlinear spatially periodic or quasiperiodic standing waves (SWs) in one-dimensional lattices of coupled anharmonic oscillators.…
Analytic Conditions for Targeted Energy Transfer between Nonlinear Oscillators or Discrete Breathers
S. Aubry, G. Kopidakis, A. M. Morgante +1
It is well known that any amount of energy injected in a harmonic oscillator which is resonant and weakly coupled with a second harmonic oscillator, tunnels back and forth between…
Oscillatory Instabilities of Standing Waves in One-Dimensional Nonlinear Lattices
Anna Maria Morgante, Magnus Johansson, Georgios Kopidakis +1
In one-dimensional anharmonic lattices, we construct nonlinear standing waves (SWs) reducing to harmonic SWs at small amplitude. For SWs with spatial periodicity incommensurate wit…
