玻色极性分子的凝聚态波函数和元激发：超越第一玻恩近似
Condensate wave function and elementary excitations of bosonic polar molecules: beyond the first Born approximation
摘要：
研究了强相互作用玻色极性分子在简谐势阱中的凝聚态波函数和元激发，在标准第一玻恩近似（FBA）之外处理了散射振幅。通过在变分法中使用适当的试波函数，已经研究了超过FBA的首阶校正的影响，并且当系统接近崩溃的相边界时，首阶校正的影响被显着增强。文中还讨论了如何在实际实验中观察到这种超越FBA的领先阶效应。
英文摘要：
We investigate the condensate wave function and elementary excitations of strongly interacting bosonic polar molecules in a harmonic trap, treating the scattering amplitude beyond the standard first Born approximation (FBA). By using an appropriate trial wave function in the variational method, effects of the leading order correction beyond the FBA have been investigated and shown to be significantly enhanced when the system is close to the phase boundary of collapse. How such leading order effect of going beyond the FBA can be observed in a realistic experiment is also discussed.
