Change the email footnote symbols to math symbols in the APS revtex

document-classesemailfootnotesmath-moderevtex

How to change the email footnote symbol shown below "*" to some other math symbols, such as the symbol with subscript "b$_1$", "b$_2$", "c$_3$", "a$_4$"? (for paper with four authors, "b$_1$" for the first author, and so on.)

\documentclass[ap, notitlepage, superscriptaddress]{revtex4-1}

 
\begin{document}

\begin{titlepage}


\author{1st Author b$_1$}
\email{[email protected]}

\author{2nd Author b$_2$}
\email{[email protected]}

\author{3rd Author c$_3$}
\email{[email protected]}

\author{4th Author a$_4$}
\email{[email protected]}

\maketitle
\end{titlepage}

\end{document}

This is a false example. I hope to change * to b$_1$, and so on others to b$_2$, c$_3$, and a$_4$.

Question:
How to change the Email symbol with definite symbols, that we can specify by hand:

  • the 1st Author with Email symbol b$_1$,
  • the 2nd Author with Email symbol b$_2$,
  • the 3rd Author with Email symbol c$_3$,
  • the 4th Author with Email symbol a$_4$.
    and so on that, we can specify each by hand.

Try this code. (Using revtex4-2}

Nine user-defined footnote marks were created for the email. (easily expanded). If any of the new ones are not used, the default mark will be used.

\documentclass[aps, notitlepage, superscriptaddress]{revtex4-2}

\makeatletter
\newcommand{\fmarki}{*}
\newcommand{\fmarkii}{\ensuremath{\dagger}}
\newcommand{\fmarkiii}{\ensuremath{\ddagger}}
\newcommand{\fmarkiv}{\ensuremath{\mathsection}}
\newcommand{\fmarkv}{\ensuremath{\mathparagraph}}
\newcommand{\fmarkvi}{\ensuremath{\|}}
\newcommand{\fmarkvii}{**}
\newcommand{\fmarkviii}{\ensuremath{\dagger\dagger}}
\newcommand{\fmarkix}{\ensuremath{\ddagger\ddagger}}
                
\def\@fnsymbol#1{{\ifcase#1\or \fmarki\or \fmarkii\or \fmarkiii\or \fmarkiv\or \fmarkv\or \fmarkvi\or \fmarkvii\or \fmarkviii\or \fmarkix \else\@ctrerr\fi}}
\makeatother
