含时密度矩阵方法的截断格式II
Truncation scheme of time-dependent density-matrix approach II
摘要：
本文改进了Bogoliubov-Born-Green-Kirkwood-Yvon族约化密度矩阵的截断格式，其中三体密度矩阵近似为二体密度矩阵，并考虑了归一化效应.截断计划的Lipkin模型进行了测试。结果表明，所得结果与精确解符合得很好。
英文摘要：
A truncation scheme of the Bogoliubov-Born-Green-Kirkwood-Yvon hierarchy for reduced density matrices, where a three-body density matrix is approximated by two-body density matrices, is improved to take into account a normalization effect. The truncation scheme is tested for the Lipkin model. It is shown that the obtained results are in good agreement with the exact solutions.
