论文摘要
使用变分原理,我们表明,bose气体中空间崩溃的条件不是由粒子之间相互作用电位的散射长度的值确定的,与粒子的结果相反,在总散射长度下应发生崩溃。
Using the variational principle, we show that the condition of spatial collapse in a Bose gas is not determined by the value of the scattering length of the interaction potential between particles contrary to the result following from the Gross--Pitaevskii equation, where the collapse should take place at a negative scattering length.
