{To the Editors of the Journal of Physical Chemistry Letters}
|

|

\opening{Dear Editors,}
|
||||
|
||||
\justifying
|
||||
Please find enclosed our manuscript entitled
|
||||
\begin{quote}
|
||||
\textit{``Pros and Cons of the Bethe-Salpeter Formalism for Ground-State Energies''},
|
||||
\end{quote}
|
||||
which we would like you to consider as a Letter in the \textit{Journal of Physical Chemistry Letters}.
|
||||
This contribution fits nicely in the section \textit{``Spectroscopy and Photochemistry; General theory''}.
|
||||
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 past few years, the Bethe-Salpeter formalism has demonstrated to be a valuable and cost-effective alternative to TD-DFT to compute excitation energies.
|
||||
It has gained significant momentum, not only in Physics, but also within the Chemistry community, and is now available in several popular quantum chemistry software packages.
|
||||
It is now a genuine multidisciplinary methodology that can be applied to materials as well as molecular systems.
|
||||
Although less popular to date, the Bethe-Salpeter formalism can also be applied to compute ground-state energies via the adiabatic-connection fluctuation dissipation formalism.
|
||||
|
||||
The present Letter provides, what we believe, are two important messages.
|
||||
On the one hand, we show that Bethe-Salpeter can provide extremely accurate total energies and equilibrium bond distances.
|
||||
We have illustrated this for 8 diatomic molecules for which we have also computed reference ground-state data using increasingly accurate coupled cluster methods.
|
||||
For the larger systems considered here, we observe that Bethe-Salpeter recovers 99\% of the CC3 correlation energy and yields outstanding equilibrium bond lengths.
|
||||
It should be stressed that such a success cannot be not reached with popular quantum chemistry methods such as MP2, CC2 or CCSD, and was never shown before.
|
||||
On the other hand, we have also observed that, in some cases, unphysical irregularities on the ground-state potential energy surfaces due to the appearance of a satellite resonance with a weight similar to that of the GW quasiparticle peak.
|
||||
|
||||
Because of the large impact of our work, we expect it to be of interest to a wide audience within the chemistry community and beyond.
|
||||
We suggest Julien Toulouse, Patrick Rinke, Michael van Setten, Timothy Berkelbach, Fabien Bruneval, Wim Klopper, Trygve Helgaker, Pina Romaniello, and Lucia Reining as potential referees.
|
||||
We look forward to hearing from you soon.
|
||||
|
||||
\closing{Sincerely, the authors.}
