Dispersion of passive tracers in velocity field with non delta-correlated noise
P. Castiglione, A. Crisanti
The diffusive properties in velocity fields whose small scales are parameterized by non -correlated noise is investigated using multiscale technique. The analytical expression o…

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…
