高密度弱相互作用玻色气体的基态能量

The ground state energy of the weakly interacting Bose gas at high density

Alessandro Giuliani, Robert Seiringer

摘要:

在弱耦合和高密度的同时限制下,证明了具有指数函数描述的排斥作用的三维玻色气体的基态能量的Lee-Huang-Yang公式.特别是,我们表明,Bogoliubov近似是准确的,在适当的参数制度,就基态能量而言。

英文摘要:

We prove the Lee-Huang-Yang formula for the ground state energy of the 3D Bose gas with repulsive interactions described by the exponential function, in a simultaneous limit of weak coupling and high density. In particular, we show that the Bogoliubov approximation is exact in an appropriate parameter regime, as far as the ground state energy is concerned.
