I want to add a symbol that looks like a (compressed) spring "\/\/\" (this is just to give a rough idea; I want the lines to be connected) above a character (in math mode). Any ideas on how to do this? (The comprehensive list doesn't seem to have such a symbol.)

Thanks!

Inspired from this question, Change vertical space in overset you can add a ''spring'' symbol above a character.

With \gluon symbol. enter image description here

\documentclass{article}
\usepackage{mathtools,amssymb}
\usepackage{wasysym}
\usepackage{graphicx}
\usepackage{scalerel}
\begin{document}
\[\overset{\lower.3em\hbox{\,\scaleobj{.4}{\gluon}}}{A}\]
\end{document}

With \photon symbol.

enter image description here

\documentclass{article}
\usepackage{mathtools,amssymb}
\usepackage{wasysym}
\usepackage{graphicx}

\begin{document}
\[\overset{\lower.1em\hbox{\,\scalebox{.5}[2.1]{\photon}}}{A}\]
\end{document}
