Dear PWSCF users,<br>
I want to know how the charge density is normalized in PWSCF. <br>
For example, I have calculated
bulk STO. The integral of charge density over the unit cell is 0.162. I
normalize it to the total number of electron which is 40.<br>
Then I calculate bulk LAO in the
unit cell of the same size, same k-point sample and same energy cutoff.
The integral of charge density over the unit cell is 0.19. The total
number of electrons is 32 for LAO.<br>
So how does PWSCF normalize charge density for different cases?<br>
Thank you.<br>
