braket

The braket extension defines the following macros for producing the bra-ket notation and set notation used in quantum mechanics

\bra{math}

\ket{math}

\braket{math}

\set{math}

\Bra{math}

\Ket{math}

\Braket{math}

\Set{math}

and the non-standard macros

\ketbra{math}

\Ketbra{math}

See the documentation for the LaTeX braket package for details of how these are used.

This extension is loaded automatically when the autoload extension is used. To load the braket extension explicitly (when using input/tex-base for example), add '[tex]/braket' to the load array of the loader block of your MathJax configuration, and add 'braket' to the packages array of the tex block.

window.MathJax = {
  loader: {load: ['[tex]/braket']},
  tex: {packages: {'[+]': ['braket']}}
};

Alternatively, use \require{braket} in a TeX expression to load it dynamically from within the math on the page, if the require extension is loaded.
