We extend high-momentum antisymmetrized molecular dynamics (HMAMD) by incorporating the short-range part of the unitary correlation operator method (UCOM) as the variational method of finite nuclei. In this HMAMD+UCOM calculation of light nuclei, HMAMD is mainly in charge of the tensor correlation with up to four-body correlation, while the short-range correlation is further improved by using UCOM. The binding energies of the $^3$H and $^4$He nuclei are calculated with HMAMD+UCOM using the AV8$'$ bare nucleon–nucleon ($NN$) interaction. The different roles of the short-range and tensor correlations from HMAMD and UCOM are analyzed in the numerical results. Compared with previous calculations based on different variational methods, this newly extended HMAMD+UCOM method can almost provide consistent results with ab initio results.

利用 3H 和 4He 的裸 NN 相互作用，酉相关算子在高动量反对称分子动力学中的作用

我们通过将酉相关算子方法 (UCOM) 的短程部分作为有限核的变分方法来扩展高动量反对称分子动力学 (HMAMD)。在这次 HMAMD+UCOM 轻核计算中，HMAMD 主要负责张量相关，最多四体相关，而使用 UCOM 进一步提高了短程相关。$^3$H 和 $^4$He 核的结合能是通过 HMAMD+UCOM 使用 AV8$'$ 裸核子-核子 ($NN$) 相互作用计算的。在数值结果中分析了来自 HMAMD 和 UCOM 的短程相关和张量相关的不同作用。与之前基于不同变分方法的计算相比，这种新扩展的 HMAMD+UCOM 方法几乎可以提供与从头算结果一致的结果。
