Template:Ket

|{{{1}}}⟩

Template documentation[view] [edit] [history] [purge]

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

This template uses {{braket}}.

Application

There is one parameter, which is the text to be displayed as the ket label.

A ket can be written: |Ψ⟩, that is {{ket|Ψ}}.

Using {{math}}, a ket can be written: $|Ψ ⟩$ , that is {{math|{{ket|Ψ}}}}.

In wiki-markup rather than LaTeX:

iħ d / dt | ψ (t) ⟩ = Ĥ | ψ (t) ⟩

that is,

{{math|1=''iħ''{{sfrac|''d''|''dt''}}{{ket|''ψ''(''t'')}} = ''Ĥ''{{ket|''ψ''(''t'')}}}}
