DESCRIPTION:Speaker: SÃ¶ren Petrat\nhosted by Robert Seiringer\nAbstract: I
n this talk we consider a quantum system of N interacting bosons in the me
an field scaling regime. We construct corrections to the Bogoliubov dynami
cs that approximate the true N-body dynamics in norm to arbitrary precisio
n. The corrections are such that they can be explicitly computed in an N-i
ndependent way from the solutions of the Bogoliubov and Hartree equations
and satisfy a generalized form of Wick's theorem. We determine the n-point
correlation functions of the excitations around the mean field\, as well
as the reduced densities of the N-body system to arbitrary precision\, giv
en only the knowledge of the two-point functions of a quasi-free state and
the solution of the Hartree equation.
