关于投影密度在Skyrme或Gogny泛函的密度相关部分中的应用的注记

Remarks on the use of projected densities in the density dependent part of Skyrme or Gogny functionals

L M Robledo

摘要:

我讨论的不足,“预计密度”处方密度依赖力/泛函计算时,追求超越平均场。的情况下,计算的目的是在对称性恢复的平均场得到的Skyrme或Gogny型的有效现实的力量被详细考虑。它示出,至少对于像旋转,平移或奇偶校验的空间对称性的恢复,上述处方产生灾难性的结果的能量,驱动的内在波函数的配置与无限变形,从而防止其使用在投影前后的变化。

英文摘要:

I discuss the inadequacy of the "projected density" prescription to be used in density dependent forces/functionals when calculations beyond mean field are pursued. The case of calculations aimed at the symmetry restoration of mean fields obtained with effective realistic forces of the Skyrme or Gogny type is considered in detail. It is shown that at least for the restoration of spatial symmetries like rotations, translations or parity the above prescription yields catastrophic results for the energy that drive the intrinsic wave function to configurations with infinite deformation, preventing thereby its use both in projection after and before variation.
