@ -1669,7 +1669,10 @@ can significantly improve the estimate of the energy using low-order perturbatio
as shown in Table~\ref{tab:RMP_shank}.
Even though the RMP series diverges at $U/t = 4.5$, the combination
of diagonal Pad\'e approximants with the Shanks transformation reduces the absolute error of
the best energy estimate to 0.002\,\%.}
the best energy estimate to 0.002\,\% using only the lowest 10 terms in the corresponding
Taylor series.}
This remarkable result indicates just how much information is contained in the first few
terms of a perturbation series, even if it diverges.
