关于受限玻色气体稳定性的注记:L.萨拉斯尼希

Note on the stability of a confined Bose gas: Comment on quant-ph/9712030 by L. Salasnich

F. Brosens, J. T. Devreese, L. F. Lemmens

摘要:

我们用解析的方法证明了当粒子间相互作用为零程吸引时,一个玻色-爱因斯坦凝聚体是不稳定的。用短程吸引相互作用代替零程相互作用,可以提高不稳定性,并导致明显的聚集,从而使粒子从凝聚体中泄漏出来。

英文摘要:

We demonstrate analytically that a Bose-Einstein condensate confined in a harmonic trap with zero-range attractive interparticle interactions is unstable if there is more than 1 boson. Replacing the zero-range interaction by a short-range attractive interaction lifts the instability, and leads to a pronounced clustering, by which the particles leak out of the condensate.
