[Pw_forum] Calculate the expectation value of orbital angular momentum

[Maciej Szary]

Dear espresso users,

I'm trying to calculate the expectation value of orbital angular 
momentum (OAM) at given k points. I'm aware that band.x can calculate 
the expectation value of the spin operator, so is there a way to do the 
same for OAM?

Thanks,
