This is for producing quantum state vectors in bra-ket notation, using wikicode, ideally with {{math}}, as an alternative to LaTeX in <math> mode.

Application

It's very easy to use. There are three parameters, use as many as needed in this order:

  1. Brakets: choose one of:
    • bra (for a bra vector),
    • ket (for a ket vector), or
    • braket (for the inner product).
  2. Symbol 1:
    • if 1 is set to bra or ket: enter the first symbol for the bra or ket,
    • if 1 is set to braket: enter the symbol for the bra part of the inner product.
  3. Symbol 2:
    • if 1 is set to bra or ket: this parameter is not needed.
    • if 1 is set to braket: enter the symbol for the ket part of the inner product.

The symbols can of course be bold, italic, underlined, any unicode symbol, etc.

Examples

Ket

A ket can be written: Template:Rangle, that is {{braket|ket|ψ}}.

Using {{math}}; a ket can be written: Template:Rangle, that is {{math|{{braket|ket|ψ}}}}.

Bra

A bra can be written: ⟨ψ|, that is {{braket|bra|ψ}}.

Using {{math}}; a bra can be written: ⟨ψ|, that is {{math|{{braket|bra|ψ}}}}.

Braket

The inner product of the kets Template:Rangle and Template:Rangle can be written: = , that is {{braket|braket|ψ|ξ}} = {{braket|braket|ξ|ψ}}<sup>†</sup>.

Using {{math}}; the inner product of the kets Template:Rangle and Template:Rangle can be written: = , that is {{math|{{braket|braket|ψ|ξ}} {{=}} {{braket|braket|ξ|ψ}}<sup>†</sup>}}.
