General static observables

[malte-schueler]

Hi! As I see correctly, the static observables implemented so far are all observables which can be expressed in density operators. I would like to implement <L^2> and <J^2> for a multi-orbital anderson model but don't imidialtly see how to do so straightforwardly. Are there any plans to implement this? Or could you give any advice on how to proceed?
Thanks!

Hi @malte-schueler , This is all possible, however it would be useful if you write it down in second quantized form to save me some time.
