I want to tex the following MWE:
\documentclass[
amsmath,
onecolumn,
aps,
prb,
notitlepage,
10pt
]{revtex4-1}
\usepackage{physics}
\newcommand{\mrm}[1]{\mathrm{#1}}
\newcommand{\eps}{\epsilon}
\begin{document}
\begin{align}
\abs{ _u\mel{\nu,\vb*{0}}{\vb*{k}\cdot\vb*{p}}{\nu',\vb*{0}}_u }^2
\end{align}
\end{document}
The problem is in the that the u in front of the matrix element (\mel
is from the physics package) is too far away from the left bracket (<). Can I somehow reduce that space?

A solution using

\prescript
macro is the key.
