\opening{Dear Editors,}
|
|||
|
|
|
|||
|
|
\justifying
|
|||
|
|
Please find enclosed our manuscript entitled \textit{``A similarity renormalization group approach to Green's function methods''}, which we would like you to consider as a Regular Article in the \textit{Journal of Chemical Theory and Computation}.
|
|||
|
|
This contribution has never been submitted in total nor in parts to any other journal, and has been seen and approved by all authors.
|
|||
|
|
|
|||
|
|
In the present contribution, we apply the similarity renormalization group (SRG) approach to the well-known $GW$ approximation of many-body perturbation theory.
|
|||
|
|
We show that the SRG transformation allows us to derive, from first principles, a new static and hermitian expression for the self-energy that can be directly employed in self-consistent $GW$ calculations.
|
|||
|
|
As shown on a large set of molecules, the resulting SRG-based regularized self-energy significantly accelerates the convergence of $GW$ calculations and slightly improves the overall accuracy.
|
|||
|
|
We hope that these new technical developments will broaden the applicability of Green’s function methods in the molecular electronic structure community and beyond.
|
|||
|
|
|
|||
|
|
Because of the novelty of this work and its potential impact in quantum chemistry and condensed matter physics, we expect it to be of interest to a wide audience within the chemistry and physics communities.
|
|||
|
|
We suggest Francesco Evangelista, Timothy Berkelbach, George Booth, Alexander Sokolov, and Xavier Blase as potential referees.
|
|||
|
|
We look forward to hearing from you soon.
|
|||
|

\closing{Sincerely, the authors.}
