+theory \cite{Moller_1934} which remains one of the most popular methods for computing the electron correlation energy, 
+an old yet important concept, first introduced by Wigner \cite{Wigner_1934} and later defined by L\"owdin. \cite{Lowdin_1958} 
 In this approach, the exact electronic energy is estimated by constructing a perturbative correction on top
 of a mean-field Hartree--Fock (HF) approximation.\cite{SzaboBook}
 The popularity of MP theory stems from its black-box nature and relatively low computational scaling,
