From semi-classical to quantum many body
through normal forms

Milano, December 17-20, 2019

In recent years there has been a growing activity on the problem of justification of mean field equations for many body quantum systems, with particular attention to the semiclassical limit. The methods used are often reminescent of averaging and normal form methods typically used in the theory of dynamical systems.
Furthermore, semiclassical methods have shown that there are deep connections between dynamical properties of a Hamiltonian system and the spectral properties of the corresponding quantum operator. The purpuse of this workshop is to discuss the relationships between normal form methods, spectral theory and effective equations in order to try to export the corresponding techniques from one field to the others.

There will be two minicourses, by B. Schlein and S. Vũ Ngọc, and seven talks.
