矩阵表示的核子对近似

Nucleon-pair approximation with matrix representation

Y. Lei, Y. Lu, Y. M. Zhao

摘要:

本文提出了一种核子对近似(NPA)方法,其中集体核子对用反对称矩阵表示,核子对之间的交换用矩阵乘法给出,避免了角动量耦合和再耦合。因此,本方法显著简化了NPA计算。此外,它是在相同的基础上制定的有和没有同位旋。

英文摘要:

In this paper, we propose an approach of the nucleon-pair approximation (NPA), in which the collective nucleon pairs are represented in terms of antisymmetric matrices, and commutations between nucleon pairs are given by using matrix multiplication that avoids angular-momentum couplings and recouplings. Therefore the present approach significantly simplifies the NPA computation. Furthermore, it is formulated on the same footing with and without isospin.
