Title: "Phase-space approach to bosonic mean field asymptotic: an overview"

Summary:
The bosonic mean field approximation can be presented as an infinite
dimensional semiclassical asymptotics. This was known for a long time at
the formal level or on some specific examples, after Bogoliubov, Berezin
and Hepp for example. Benefitting from the advances in semiclassical
analysis of the nineties, we went back to this point of view in a series
of works with Zied Ammari. This analysis shows deep interrelations between
quantum field theory, microlocal analysis, stochastic processes and
measure transportations. It also provides new results and new quantities
which motivate forthcoming theoretical or numerical works.
