弱相互作用玻色气体的低能谱和动力学

Low-energy spectrum and dynamics of the weakly interacting Bose gas

Lea Boßmann

摘要:

我们考虑气体的N玻色子的相互作用的平均场标度制度。我们回顾了它的低能谱、本征态和动力学的渐近展开的证明,它提供了对Bogoliubov理论在1/N中所有阶的修正。这是基于与S. Petrat,P. Pickl,R. Seiringer和A.索弗此外,我们还导出了基态单体约化密度矩阵的完全渐近展开式。

英文摘要:

We consider a gas of N bosons with interactions in the mean-field scaling regime. We review the proof of an asymptotic expansion of its low-energy spectrum, eigenstates and dynamics, which provides corrections to Bogoliubov theory to all orders in 1/N. This is based on joint works with S. Petrat, P. Pickl, R. Seiringer and A. Soffer. In addition, we derive a full asymptotic expansion of the ground state one-body reduced density matrix.
