Dirac notation (bra/ket) LaTeX commands for use in Jupyter notebooks

braket.ipynb

Sorry to bother you with that, but could you advise me how to add this configuration into jupyter notebook? I assume I need the nbextension latex_envs which i do have, but I am not sure which json file i can add this configuration to and where to find that.
Kind regards!

Been a while since I looked at this. I tested this again with Jupyter Notebook, with default Conda installation. Nothing special was required...just entering the code into markdown worked. The \newcommand lines create new bra, ket, and brakes LaTeX commands that you can then use in your own markdown. As long as those \newcommand lines appear in your notebook before the commands are invoked, it should just work.

To see the Markdown in action, you should download the .ipynb and view it, but I'm copying all the markdown below so you can see the Markdown that was rendered in the notebook.

$$\newcommand{\ket}[1]{\left|{#1}\right\rangle}$$
$$\newcommand{\bra}[1]{\left\langle{#1}\right|}$$
$$\bra{\Psi}\Omega\ket{\Psi}$$

$$\newcommand{\braket}[2]{\left\langle{#1}\middle|{#2}\right\rangle}$$
$$\braket{\Psi}{\Psi}$$
$$\braket{\frac{\Psi}{2}}{\Psi}$$

\begin{align}
\braket{Paw_L}{Paw_R} = 0
\end{align}

Thank you for your quick reply, I was able to make it work thankfully.

Looks like this renders correctly with GitHub's .ipynb gist preview MathJax now?

@westurner apparently!
