Remove 'thanks' footnote from second bibliography when using revtex

Question

I have two bibliographies in a latex document that's using revtex with the prb journal style. I also use the \thanks{} command in constructing the title page. Due to the prb style, the footnote associated with the thanks is displayed in the bibliography.

However, it shows in both bibliographies and I only want it to show in the first. Can the footnote be removed from the second bibliography?

EDIT: To clarify, I still want to keep the thanks footnote in the first bibliography when removing it from the second bibliography.

A simple example is the following:

\documentclass[prb]{revtex4-1}

\begin{document}

\title{Title}
\author{Author}
\thanks{thanks}
\maketitle

This is a citation \cite{ref1} and this is another \cite{ref2}.

\begin{thebibliography}{36}
\bibitem{ref1} Reference 1.
\end{thebibliography}

\begin{thebibliography}{36} 
\bibitem{ref2} Reference 2.
\end{thebibliography}

\end{document}

Answer 1

Here is a hack that does what you want, inspired by line 2434 in revtex4-1.cls. Not sure if this is legal, I'm new to macros.

\documentclass[prb]{revtex4-1}
%\usepackage[paperheight=6cm,paperwidth=10cm,margin=0.5cm]{geometry}

\makeatletter
\def\clearfmfn{\let\@FMN@list\@empty}    % <- clears the list of frontmatter footnotes
\makeatother

\begin{document}

\title{Title}
\author{Author}
\thanks{thanks}
\maketitle

This is a citation \cite{ref1} and this is another \cite{ref2}.

\begin{thebibliography}{36}
\bibitem{ref1} Reference 1.
\end{thebibliography}

\clearfmfn                               % <- call the command after 1st bibliography

\begin{thebibliography}{36}
\bibitem{ref2} Reference 2.
\end{thebibliography}

\end{document}
