Re: [Pw_forum] Backward compatibility issue on elph matrix elements between QE 4.0.3 and 5.1.2

2015-06-28 Thread Samuel Poncé
Dear Paolo, Thank you for your reply. The elphmat internal variable should not be a werewolf as it represent **2, a variable that directly enters physicals quantities like the zero-point renormalization. Following your advice I could narrowed it down so far between revision 5000 and 5300 (see be

Re: [Pw_forum] what origin of difference in obtained energy from Dmol3 and ESPRESSO?

2015-06-28 Thread Ari P Seitsonen
Dear Ehsan targholi, In general no: You should have exactly the same pseudo potential for both. Then there could still remain other potential, numerical sources for differences (treatment of the evaluation of exchange-correlation, basis set, ...), but those would be much smaller. Thus,

thanks a lot for your proper answer. my notion of your answer is that if i change the all-electron trearment to pseudo potential treatment in Dmol3, it give the same energy with ESPRESSO. is it true? best regards On Sun, Jun 28, 2015 at 3:28 PM, Ari P Seitsonen wrote: > > Dear Ehsan targholi,

2015-06-28 Thread Ari P Seitsonen
Dear Ehsan targholi, Keyword here is "pseudo potential" (QE), versus (probably) all-electron calculation in Dmol3. In practise one is almost always interested in energy differences between different systems but the same approach, and thus total energies never appear there. Greetings f

[Pw_forum] meaning of Lowdin charges with non-collinear magnetizations

2015-06-28 Thread Yi Wang
Dear everyone, I'm doing a non-collinear magnetization calculation(non spin-orbit). I wanted to know the magnetic moment on each atom, thus I performed the Lowdin charge calculation with projwfc.x. The code gives the the results of "polarization", "spin up", "spin down", and "total charge".
