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