I am getting the following error:

"Package simpler-wick Warning: I have reached the end of \wick with some unclosed contractions on input line 8123."

My code is simply:

$\wick{\c1 \psi \ket{\c1 p}}$

I am getting the correct output. But I would like to understand the cause of this error and eliminate it.

    How did you define \ket? If you are using the physics package then the advice is not to use the physics package because it is outdated. The following works without errors or warnings: \documentclass{article} \usepackage{simpler-wick} \usepackage{mathtools} \DeclarePairedDelimiter\bra{\langle}{\rvert} \DeclarePairedDelimiter\ket{\lvert}{\rangle} \begin{document} $\wick{\c1 \psi \ket{\c1 p}}$ \end{document}. – Marijn Jul 10 '21 at 15:21
  • See https://tex.stackexchange.com/questions/214728/braket-notation-in-latex for more information on \ket. – Marijn Jul 10 '21 at 15:22
  • Later I tried with rangle langle rvert and lvert. Still getting the error – Samapan Bhadury Jul 10 '21 at 17:04
  • If you still get the error then you need to add a small complete document to your question, similar to the code in the answer below, or the code in my first comment. This document should be as small as possible while still being complete (it should be possible to compile wihtout adding anything) and it should show the error of course. To make such a document you can start with your current code and try to delete as much as you can while the error remains. Then add the code to your question with the edit button. – Marijn Jul 10 '21 at 17:41

The following code works without the warning:

\documentclass{article}
\usepackage{simpler-wick}
\begin{document}
$\wick{\c1\psi\mid \c1 p\rangle}$
\end{document}

enter image description here

It complies perfectly at overleaf: enter image description here
