Abstract:

The oscillations of linear triatomic molecule with the first atom driven at a constant velocity upsilon are studied numerically. As upsilon increases, we observe a sequence of transitions from quasiperiodicity to chaos, mode locking, chaos, model locking, chaos, another mode locking and then to chaos before atoms break off. The largest Lyapunov exponent does not rise linearly with the driven velocity. The mode locking structure for the last onset to chaos has a universal fractal dimension 0.871 0.001 at a winding number far from the golden mean.
