论文摘要
我们研究了多体相关性对三个和两个空间维度的单个成分超冷的费米液体具有纯粹排斥粒子间相互作用的单个成分超冷的费米液体的地面特性的影响。我们已经采用了费米 - hypernetted-链欧拉格拉格近似，并观察到，在软核半径的中间值和较大的耦合强度的中间值下，相关能对地基能量的贡献变得显着。对于大小的软核半径，相关能量可以忽略不计，而基态能量接近Hartree-Fock值。主峰在静态结构因子中的位置和均质流体相中的成对分布函数信号信号信号量子液滴晶体的形成，每个液滴内部的几个颗粒。
We investigate the effects of many-body correlations on the ground-state properties of a single component ultra-cold Rydberg-dressed Fermi liquid with purely repulsive inter-particle interactions, in both three and two spatial dimensions. We have employed the Fermi-hypernetted-chain Euler-Lagrange approximation and observed that the contribution of the correlation energy on the ground-state energy becomes significant at intermediate values of the soft-core radius and large coupling strengths. For small and large soft-core radii, the correlation energy is negligible and the ground-state energy approaches the Hartree-Fock value. The positions of the main peaks in static structure factor and pair distribution function in the homogeneous fluid phase signal the formation of quantum droplet crystals with several particles confined inside each droplet.
