Package braket:
Dirac bra-ket and set notations.

Provides macros to typeset bra-ket notation, as well as set specifiers, with a single (“|”) or a double (“||” or (“\|”) vertical bar specifier in between two bracketed parts. Each macro comes in a fixed-size version and an expanding version.

If the package finds itself operating under e-tex, it uses the extended primitive \middle for more reliable results
