Résumé

I will explain how equations of Classical Mechanics, defined from Poisson structures, can emerge from Quantum Mechanics. This is done via self-consistency equations, which in turn imply an extended quantum dynamics. This situation generically appears for quantum systems with long-range interactions, as in the so-called BCS theory of (conventional) superconductivity.
