+
+\opening{Dear Editors,}
+
+Please find attached a manuscript entitled
+``Taming the fixed-node error in diffusion Monte Carlo via range separation'', which
+we would like to submit as an invited article in the \textit{Journal of Chemical Physics} for the JCP Special Topic on Frontiers of Stochastic Electronic Structure Calculations.
+
+In this manuscript, we combine range-separated density functional theory (RS-DFT) and
+selected configuration interaction using the CIPSI algorithm to build
+multi-determinant trial wave functions for diffusion Monte Carlo calculations.
+Compared to conventional CIPSI wave functions, we are able to reduce by several
+orders of magnitude the number of determinants of the CI expansion, and we can
+obtain fixed-node DMC energies lower than the DMC energy obtained with the full
+CI trial wave function within the same basis set. Benchmarks calculations have shown
+that the proposed scheme can provide a mean absolute error of 2~kcal/mol on the
+atomization energies of the 55 molecules of the Gaussian-1 set with a
+reproducible protocol.
+
+Because of the large potential impact of our work, we expect it to be of great
+interest to a wide audience within the electronic structure community. 
+We suggest Lubos Mitas, Andrea Zen, Seiichiro Ten-no, Michele Casula, Matus
+Dubecky, Manolo Per, Sandeep Sharma, and Eric Neuscamman as potential referees.
+We look forward to hearing from you soon.
+
+\closing{Sincerely, the authors.}
