Spectral properties of quantum -body systems versus chaotic properties of their mean field approximations
Patrizia Castiglione, Giovanni Jona-Lasinio, Carlo Presilla
We present numerical evidence that in a system of interacting bosons there exists a correspondence between the spectral properties of the exact quantum Hamiltonian and the dynamica…

Chaotic properties of quantum many-body systems in the thermodynamic limit
Giovanni Jona-Lasinio, Carlo Presilla
By using numerical simulations, we investigate the dynamics of a quantum system of interacting bosons. We find an increase of properly defined mixing properties when the number of…
