Abstract

A numerical study and a theoretical analysis of the two-wave Hamiltonian system is presented, to reveal and explain a mode-locking phenomenon and its persistency. For appropriate sets of parameters and initial conditions, the motion associated with this system consists of three distinct types: regular quasiperiodic motion, stochastic states and regular motion, having some of the modes of the spectrum locked. A bifurcation parameter is established, determining what kind of motion the system follows, and responsible for the transitions between the different types of motion. The persistency of the locking of the modes realised when this parameter is high enough is found to be induced by higher order resonance effects.
