Title:

Abstract:

After a short review on why the increasing number of degrees of  freedom makes possible to approximate many-body quantum mechanics, an  intrinsically linear evolution, with a nonlinear single-body equation,
the proof is sketched of a new method for deriving the nonlinear  Hartree equation form the mean field limit
$N\to\infty$ for a system of $N$ bosons which allows us to obtain  convergence estimates uniform with respect to the Planck constant.
