摘要：

We consider the ground state and the low-energy excited states of a system of N identical bosons with interactions in the mean-field scaling regime. For the ground operators, which yields corrections to a central limit theorem to any order in 1/vN. For state, we derive a weak Edgeworth expansion for the fluctuations of bounded one-body suitable excited states, we show that the limiting distribution is a polynomial times a normal distribution, and that higher-order corrections are given by an Edgeworth-type expansion.
