Then, a static BSE calculation is performed in the 1h1p sector with a two-body term dressed with correlation stemming from $GW$. The dynamical version of BSE [where the BSE kernel is explicitly treated as frequency-dependent in Eq.~\eqref{eq:BSE}] takes partially into account the 2h2p configurations. \cite{Strinati_1980,Strinati_1982,Strinati_1984,Strinati_1988,Rohlfing_2000,Romaniello_2009b,Loos_2020h,Authier_2020,Monino_2021,Bintrim_2022} +\titou{More equations and/or figures?} %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \section{Connection between $GW$ and CC} @@ -611,6 +612,7 @@ To determine the 2h1p and 2p1h amplitudes, $t_{ija,p}^{\text{2h1p}}$ and $t_{iab t_{iab,p}^{\text{2p1h}} & \leftarrow t_{iab,p}^{\text{2p1h}} - \qty( \Delta_{iab,p}^{\text{2p1h}} )^{-1} r_{iab,p}^{\text{2p1h}} \end{align} \end{subequations} +\titou{Maybe analyze further these equations and mention that we obtain an eigensystem, not an energy like in CC?} The quasiparticle energies $\e{p}{GW}$ are thus provided by the eigenvalues of $\be{}{} + \bSig{}{\GW}$, where \begin{equation}
