Gross-Pitaevskii体系中囚禁玻色子的最优速率的玻色-爱因斯坦凝聚

Bose-Einstein Condensation with Optimal Rate for Trapped Bosons in the Gross-Pitaevskii Regime

Christian Brennecke, Benjamin Schlein, Severin Schraven

摘要:

本文考虑了一种玻色气体,该气体由位于$\mathbb{R}^3$中的$N$粒子组成,被外场捕获,并通过散射长度为$N^{-1}$的二体势相互作用。我们证明了低能量状态下表现出完整的玻色-爱因斯坦凝聚的最佳速率,推广以前的工作在\cite{BBCS1, BBCS4},限制平移不变系统。这扩展了\cite{NNRT}中最近的结果,消除了散射长度大小的小假设。

英文摘要:

We consider a Bose gas consisting of $N$ particles in $\mathbb{R}^3$, trapped by an external field and interacting through a two-body potential with scattering length of order $N^{-1}$. We prove that low energy states exhibit complete Bose-Einstein condensation with optimal rate, generalizing previous work in \cite{BBCS1, BBCS4}, restricted to translation invariant systems. This extends recent results in \cite{NNRT}, removing the smallness assumption on the size of the scattering length.
