Nonlinear dynamics of Bohmian trajectories in a double-well potential

We investigate the dynamics of a quantum particle in a one-dimensional double-well potential within the framework of Bohm's quantum mechanics. We find that the behavior of the trajectories is linked to the degree of complexity of the initial wave packet. By increasing the complexity of the wave packet we obtain trajectories that are either periodic, quasiperiodic, or chaoticlike.
