Abstract
By using numerical simulations, we investigate the dynamics of a quant um system of interacting bosons. We find an increase of properly defin ed mixing properties when the number of particles increases at constan t density or the interaction strength drives the system away from inte grability. A correspondence with the dynamical chaoticity of an associ ated c-number system is then used to infer properties of the quantum s ystem in the thermodynamic limit.
