[Tex/LaTex] Footnote does not appear

footnotes

As the title says.

\documentclass[reprint, prb]{revtex4-1}
\usepackage{scrextend}

\begin{document}

some text here.
\footnote{aaa}

\end{document}

This does not produce any footnote. It simply gives the above mentioned warning. (My main text is much larger but I just wanted to give an example. In the main text it actually also give a warning: Citation Note0 on page 1 is undefined.)

I have looked into other similar problems here in TS but nothing solving my problem. Thanks.

By default, revtex4-1 puts footnotes in the bibliography. This can be disabled with nofootinbib but prb puts them at the start of the bibliography anyway. So to get footnotes at the bottom of the page, you'd need:

\documentclass[reprint, nofootinbib]{revtex4-1}
\usepackage{scrextend}

\begin{document}

some text here.
\footnote{aaa}

\end{document}

Footnotes at bottom of page

Otherwise, you need to typeset your bibliography for the notes to show up:

\documentclass[reprint, prb]{revtex4-1}
\usepackage{scrextend}

\begin{document}

some text here.
\footnote{aaa}

\bibliography{apssamp}

\end{document}
