基于弱耦合极限和强耦合极限的自洽组合，我们引入密度泛函理论来研究强关联偶极和离子超冷玻色子和费米子气体的基态性质。与传统的密度泛函方法相反，我们的公式不需要事先计算相互作用的均匀气体，因此非常适合于处理具有可调谐的长程相互作用的系统。由于它在强关联区域的渐近精确度，形式主义适用于标准平均场理论失效的系统。
We introduce a density functional formalism to study the ground-state properties of strongly correlated dipolar and ionic ultracold bosonic and fermionic gases, based on the self-consistent combination of the weak and the strong coupling limits. Contrary to conventional density functional approaches, our formalism does not require a previous calculation of the interacting homogeneous gas, and it is thus very suitable to treat systems with tunable long-range interactions. Because of its asymptotic exactness in the regime of strong correlation, the formalism works for systems in which standard mean-field theories fail.
