摘要

用于计算使用一组Hartree-Fock-Bogoliubov波函数进行发生器坐标方法计算所需的重叠的Pfaffian公式被推广到每个HFB状态在跨越希尔伯特空间的不同子空间的不同任意基中展开的情况。将所得公式与前人的结果进行了比较，证明其完全等价。对文献中得到的等效公式进行了讨论。

Pfaffian formulas for non equivalent bases

Pfaffian formulas used to compute overlaps necessary to carry out generator coordinate method calculations using a set of Hartree-Fock-Bogoliubov wave functions, are generalized to the case where each of the HFB states are expanded in different arbitrary bases spanning different sub-space of the Hilbert space. The formula obtained is compared with previous results proving to be completely equivalent to them. A discussion of equivalent formulas obtained in the literature is carried out.
