The dynamic structure factor of a Bose-Einstein condensate in an optical lattice, momentum and energy rates imparted to the condensate are analyzed in detail as the function of both the lattice depth and the strength of the two-body interaction. Our investigation shows that the lattice depth strongly affects the dynamic structure factor. An oscillating behavior of both the static structure factor and excitation strength as a function of the momentum transfer has been developed. We also show how interatomic interaction affects these processes and discuss the conditions for possible experimental realization. 相似文献

为探究主流烟气中TSNA、HCN的释放量对人体健康的影响,采用离体细胞培养的方法来检测烟气浓缩物的细胞毒性、动式被动吸烟小鼠急性毒性试验来检测烟气的急性毒性,为卷烟的安全性评价提供毒理学依据.结果表明卷烟烟气冷凝物(CSC)中TSNA、HCN的含量与其生物加权综合毒性大小并没有明显的线性关系. 相似文献
