Dear Andrea, Thanks for your reply. I am aware of the physics that you have pointed out.
Nevertheless, what i desire to obtain the 'j' states which are defined clearly for example in the silicon system, after considering the spin-orbit coupling, the 1st and 2nd valence band are degenerate: prepared by taking the linear superposition of: j = 1/2, j = -1/2. Is there any command in QE, which i can use to obtain these exact states, rather than their superposition?
