When using superscript formatting for citations, the citations are grouped in the superscript with either a comma (if there are two) or an en-dash (if there are more than two). However, if I have a footnote and a citation that are sequential, then there is no comma in the superscript, just the two numbers side-by-side.
example.tex:
\documentclass[aip]{revtex4-2}
\begin{document}
Text\cite{Ref1,Ref2}
Text\footnote{Blah}\cite{Ref1}
\bibliography{test}
\end{document}
and test.bib:
@article{Ref1,
title = {Tit1},
author = {Aut1}
}
@article{Ref2,
title = {Tit2},
author = {Aut2}
}
Produce
Is there a way to group together mixed footnote and citation references like the two citations?
