I searched in LibreOffice Math to enter Bra and Ket Vectors under the brackets section but only the inner product of the Dirac notation is provided. There is also no outer product notation as well.
Steps to Reproduce:
1.Launch LibreOffice Math
only <|> and <> bracket can be seen
there should be brackets <| , |> and |><| in the software
Reproducible: Couldn't Reproduce
User Profile Reset: No
It will be good to cater for the all the symbols that are used in maths

Not clear we need predefined paired brackets. Beyond what scalable StarMathML markup provides; e.g.:
left langle left lline <?> right rline right rangle
left rangle left lline <?> right rline right langle
left lline left rangle <?> right langle right rline
But OK I guess.

Exemple imported from Egation 3.0
With this example imported from Eguation 3.0, it seems to be no issue to write and reproduce it the same way into LO.
I agree with Jacques in comment #2. No problem to reproduce Dirac notation (Ket & Bra). So closing as WorksForMe.
