Three-wave resonant interactions in the diatomic chain with cubic anharmonic potential: theory and simulations

A. Pezzi, G. Deng, Y. Lvov +2

We consider a diatomic chain characterized by a cubic anharmonic potential. After diagonalizing the harmonic case, we study in the new canonical variables, the nonlinear interactio…
