Dear Lun Yue,
The reference is written in the header of that routine.

Obviously the PP/src/compute_ppsi.f90 routine is crucial, but I dunno which formula is used there. A reference to a paper would be greatly appreciated!

The LDA+U does not work in this case because there is a missing term, see Eq. (53) in PRB 101, 064305 (2020). > Is there a way to circumvent this on Quantum Espresso? I do not know any apart from adding the missing term.

Is there a way to calculate the momentum matrix element in PBE+U on QE? I encounter this error: 'Error in routine write_p_avg (1): write_p_avg not working with LDA+U'. Is there a way to circumvent this on Quantum Espresso?
