BRETEAUX, Sébastien. Higher order terms for the quantum evolution of a Wick observable within the Hepp method. Cubo [online]. 2012, vol.14, n.2, pp. 91-109. ISSN 0719-0646.  doi: 10.4067/S0719-06462012000200006.

The Hepp method is the coherent state approach to the mean field dynamics for bosons or to the semiclassical propagation. A key point is the asymptotic evolution of Wick observables under the evolution given by a time-dependent quadratic Hamiltonian. This article provides a complete expansion with respect to the small parameter which makes sense within the infinite-dimensional setting and fits with finite-dimensional formulae.
