我们证明了跨越多个主要壳的真实壳模型蒙特卡罗（SMMC）计算的可行性，使用真实的相互作用，其不良的饱和度和壳特性已通过新开发的通用处方得到纠正。特别关注平移不变性的近似恢复。模型空间由完整的 sd-pf 壳组成。我们在研究中包括一些众所周知的 T=0 核和 N=20,28 附近的几个不稳定的富中子核。结果表明，SMMC 计算可以通过几乎无参数的相互作用重现结合能、B(E2) 跃迁和其他可观测量。对深层相关性的本质获得了一些有趣的见解。先前研究的有效性得到了证实。
We demonstrate the feasibility of realistic shell-model Monte Carlo (SMMC) calculations spanning multiple major shells, using a realistic interaction whose bad saturation and shell properties have been corrected by a newly developed general prescription. Particular attention is paid to the approximate restoration of translational invariance. The model space consists of the full sd-pf shells. We include in the study some well-known T=0 nuclei and several unstable neutron-rich ones around N=20,28. The results indicate that SMMC calculations can reproduce binding energies, B(E2) transitions, and other observables with an interaction that is practically parameter free. Some interesting insight is gained into the nature of deep correlations. The validity of previous studies is confirmed.
