阱中稀气体的玻色-爱因斯坦凝聚

Bose-Einstein Condensation of Dilute Gases in Traps

Elliott H. Lieb, Robert Seiringer

摘要:

最近的研究表明,被限制在外部陷阱势中并通过排斥性两体力相互作用的玻色子气体的基态在稀极限下表现出完全的玻色-爱因斯坦凝聚,这是第一次在物理现实的环境中对这一现象给出严格的证明。我们在这里给出一个帐户这项工作的Gross-Pitaevskii限制的粒子数$N$去无穷大与$Na$固定,其中$a$是散射长度的粒子间相互作用,测量单位的陷阱大小。

英文摘要:

The ground state of a gas of Bosons confined in an external trap potential and interacting via repulsive two-body forces has recently been shown to exhibit complete Bose-Einstein condensation in the dilute limit, yielding for the first time a rigorous proof of this phenomenon in a physically realistic setting. We give here an account of this work about the Gross-Pitaevskii limit where the particle number $N$ goes to infinity with $Na$ fixed, where $a$ is the scattering length of the interparticle interaction, measured in units of the trap size.
