Dear QE Users<br><br>My calculated "Lowdin Charge" values are "positive" as shown below. I thought that they must be the charge of the valence electron ! but the sign is positive. Also, I don't know that a pseudopotential package like Quantum Espresso considers the "core" charge to be calculated or not ? <br>
