I guess projwfc with option kresolveddos can project Bloch wavefunction
of a selected k-point onto atomic reference (i.e. arbitrary)
wavefunctions. I'm not sure that it is what you want.

Would you mind explaining? It is not clear to me that Bloch
wavefunctions are real space objects. Wannier functions are clearly real
space, but they are clearly not "wavefunctions" (i.e. they are not
stationary states of the crystal Hamiltonian).
cheers

Dear Lorenzo,
Thank you for your reply, but my question is "Can QEproject selected
electronic states of selected atoms into the momentum space?" Clearly
wave-functions are things in the real space not the momentum space.

Dear Jibiao,
I'm not sure if I understand your question. Quantum ESPRESSO can and
does compute wavefunctions and Kohn-Sham energy bands at given
k-points. It is actually the main thing it does.
kind regards

Dear All,
In condensed matter physics, projecting electronic states of targeted
atoms into the momentum space is definitely an important tool to
study electronic structures of materials. I am writing this short
email to get answer whether QE has the functionality to do like this.
May I project either all or selected electronic states of selected
atoms into the k-space in QE?
