AI总结:
本文证明了在局域密度近似下,Kohn-Sham模型的Born-Oppenheimer势能面在小核间距时与Thomas-Fermi理论一致,并证明了最小化构型中核间距存在与核电荷无关的下界。
摘要:
我们证明了在Kohn-Sham理论中,Born-Oppenheimer势能面在小核间距$R$下与Thomas-Fermi理论中的相应势能面行为一致,误差为$o(R^{-7})$。我们还证明了,如果存在最小化构型,则核的最小距离大于某个与核电荷无关的常数。
英文摘要:
We show that the Born-Oppenheimer potential energy surface in Kohn-Sham theory behaves like the corresponding one in Thomas-Fermi theory up to $o(R^{-7})$ for small nuclear separation $R$. We also prove that if a minimizing configuration exists, then the minimal distance of nuclei is larger than some constant which is independent of the nuclear charges.
