- Bras
The superposition of states can be written ⟨p| + ⟨q| + ⟨χ| + ⟨ψ|, which is inline with the text.
Another superposition of states: ⟨P| + ⟨Q| + ⟨Φ| + ⟨Ψ|, again inline.
The superposition of states can be written {{langle}}p| + {{langle}}q| + {{langle}}χ| + {{langle}}ψ|, which is inline with the text.
Another superposition of states: {{langle}}P| + {{langle}}Q| + {{langle}}Φ| + {{langle}}Ψ|, again inline.
- Tables (also hidden boxes)
Due to the vertical bar | used in template coding, the doc code | must be used when bra–ket notation is used in tables, else some parts will not show up because of code interference.
The correct way:
More information Left bracket alone, Bra ...
Left bracket alone |
Bra |
⟨Φ + ⟨Ψ |
⟨Φ| + ⟨Ψ| |
Close
and the wrong way:
More information Left bracket alone, Bra ...
Left bracket alone |
Bra |
⟨Φ + ⟨Ψ |
+ ⟨Ψ| |
Close
The correct way:
{| class="wikitable"
! Left bracket alone
! Bra
|-
| {{langle}}Φ + {{langle}}Ψ
| {{langle}}Φ| + {{langle}}Ψ|
|}
and the wrong way:
{| class="wikitable"
! Left bracket alone
! Bra
|-
| {{langle}}Φ + {{langle}}Ψ
| {{langle}}Φ| + {{langle}}Ψ|
|}
- In conjunction with {{rangle}}
One sum of inner products is ⟨p|q⟩ + ⟨χ|ψ⟩, a real number.
A sum of average values could be ⟨P|E|Q⟩ + ⟨Φ|p|Ψ⟩, another real number.
One sum of inner products is {{langle}}p|q{{rangle}} + {{langle}}χ|ψ{{rangle}}, a real number.
A sum of average values could be {{langle}}P|''E''|Q{{rangle}} + {{langle}}Φ|''p''|Ψ{{rangle}}, another real number.
The average of a quantity q may be written ⟨q⟩. The root mean square is then √⟨q2⟩, i.e. square every value, then average, then take the root.
The average of a quantity ''q'' may be written {{langle}}''q''{{rangle}}. The root mean square is
then √{{langle}}''q''<sup>2</sup>{{rangle}}, i.e. square every value, then average, then take the root.
