We consider a system ofNbosons in the mean-field scaling regime for a class of interactions including the repulsive Coulomb potential. We derive an asymptotic expansion of the low-energy eigenstates and the corresponding energies, which provides corrections to Bogoliubov theory to any order in$1/N$.

弱相互作用玻色子的低能激发的渐近扩展

我们考虑一个系统ñ平均场标度体系中的玻色子，用于一类相互作用，包括排斥的库仑势。我们推导出低能本征态和相应能量的渐近展开式，这为 Bogoliubov 理论提供了任何阶的修正$1/N$.
