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.en10.1103/PhysRevLett.115.033006info:eu-repo/semantics/closedAccessArticle115326230790Q1WOS:000357864800008Q1
