A recent study \href{https://doi.org/10.1063/5.0089317}{[J. Chem. Phys. 156, 231101 (2022)]} has linked these convergence issues to the intruder-state problem. In this work, a perturbative analysis of the similarity renormalization group (SRG) approach is performed on Green's function methods. -The resulting SRG-based regularized self-energy significantly accelerates the convergence of self-consistent $GW$ methods. -Furthermore, the SRG formalism enables us to derive, from first principles, the expression of a new naturally Hermitian form of the static self-energy that can be employed in quasiparticle self-consistent $GW$ (qs$GW$) calculations. +The SRG formalism enables us to derive, from first principles, the expression of a new, naturally Hermitian form of the static self-energy that can be employed in quasiparticle self-consistent $GW$ (qs$GW$) calculations. +The resulting SRG-based regularized self-energy significantly accelerates the convergence of qs$GW$ calculations. %\bigskip %\begin{center} % \boxed{\includegraphics[width=0.5\linewidth]{TOC}}
