论文摘要
他的接触电位描述了原子$^4 $之间的有效相互作用，他重现了Aziz等人使用HFDHE2潜力获得的结果。使用量子蒙特卡洛计算来研究结果方程。 \ cblack每个粒子的能量和成对分布函数被研究为紫外线临界值$λ$的函数。结果表明，不仅可以正确地再现系统的平均场特性，例如能量和饱和密度，而且还可以看到非常微小的数量（例如配对分布函数）在外推$λ\ rightarrow \ infty $时都会趋向于确切的结果。
A contact potential describing an effective interaction between atomic $^4$He reproducing the results obtained with the HFDHE2 potential by Aziz et al. is employed to study the resulting equation of state by means of Quantum Monte Carlo calculations. \cblack The energy per particle and the pair distribution functions were investigated as a function of the ultraviolet cutoff $Λ$. The results suggest that not only the mean field properties of the system, such as the energy and the saturation density, are correctly reproduced, but also very microscopic quantities such as the pair distribution function are seen to converge towards the exact results when extrapolating for $Λ\rightarrow\infty$.
