摘要
We consider the many-body quantum dynamics of systems of bosons interacting through a two-body potential , scaling with the number of particles N. For , we obtain a norm-approximation of the evolution of an appropriate class of data on the Fock space. To this end, we need to correct the evolution of the condensate described by the one-particle nonlinear Schrodinger equation by means of a fluctuation dynamics, governed by a quadratic generator.
