consider the following code

\documentclass{article}
\usepackage{tensor}
\begin{document}
$$
\Bigg|0\Bigg\rangle_{\!\!\!\!\mathrm{g}}
$$
$$
 \tensor[_{\!\!\!\!\mathrm{g}}]{\Bigg\langle}{}0\Bigg|
$$
\end{document}

In the first equation I inserted \!\!\!\! since I want the \mathrm{g} very near the \rangle, and this works well. I would like also to have in the second equation but, this time neither \!\!\!\! nor \qquad, nor \hspace*{2mm} has effect. I can I get the \mathrm{g} come closer to the \langle?

For the left hand version, place the \mathrm{g} and afterwards employ the negative kern (taken here as -11mu rather than \!\!\!\! = -12mu).

\documentclass{article}
\usepackage{tensor}
\begin{document}
\[
\Biggl|0\Biggr\rangle_{\mkern-11mu\mathrm{g}}
\]
\[
 \tensor[_{\mathrm{g}\mkern-11mu}]{\Biggl\langle}{}0\Biggr|
\]
\end{document}

    @Mico Thanks. Done, with -11mu, which looks nicer. – Steven B. Segletes Jun 2 '17 at 16:40
