Abstract

We review some recent results on the norm approximation to the Schrödinger dynamics. We consider N bosons in \(\mathbb{R}^{3}\) with an interaction potential of the form N 3β−1 w(N β (xy)) with 0 ≤ β < 1∕2, and show that in the large N limit, the fluctuations around the condensate can be effectively described using Bogoliubov approximation.
