[QE-users] SCF gives different results for same input

2023-03-29 Thread Mustafa Özgür
Dear QE users,
I have 2x2x1 VS2 hexagonal structure and almost same 2 input files.

First input has 5 atomic types and the atoms are labeled as V1, V2, V3, V4 for 
Vanadium and S for Sulphur.
Second input has 2 atomic type and the atoms are labeled as V for Vanadium and 
S for Sulphur.

After running scf calculation first one gives zero total magnetization while 
second one gives non zero total magnetization.
I'm quite confused with results. Here are my input and output files;

[QE-users] Zero occupations of Hubbard levels

2023-02-06 Thread Mustafa Özgür
Hi,

I'm trying DFT+U calculation with spin orbit and noncollinear. However the 
current working version is giving the "Hubbard manifold with zero occupations 
is not allowed" error.

Then I downloaded the developed version. It is not giving any error anymore but 
occupation of hubbard levels are still zero for nscf calculation but not for 
scf calculation.

 Number of occupied Hubbard levels =3.6094 for last iteration of scf
 Number of occupied Hubbard levels =0. for nscf

Is it possible to calculate DFT+U with noncollinear? I mean is this the 
problem? or something else. Here I attached scf and nscf inputs and outputs.

Best Regards,
Mustafa.

[QE-users] Ynt: Zero occupations of Hubbard levels

2023-02-09 Thread Mustafa Özgür
Hi Iurii,

I used ultra soft pps from quantum espresso website. Scalar relativistic for 
'vc-relax' - 'relax' and full relativistic 'scf' - 'nscf'.
Problem is solved by removing 'lforcet' tag from nscf input. However It is not 
giving  "eband, Ef (eV) = ** **" energy output anymore in nscf output file.

Now I added J value too since U+J supports noncollinear calculation. But 
vc-relax calculation gives 'forces in the DFT+U+J scheme are not implemented' 
error. (Here I'm trying to apply self-consistent procedure for Hubbard and J 
parameters)

How can I overcome this problem to compute U and J parameter with hp.x code if 
it is possible? (like U and V)

Dear Mustafa,


I do not mange to reproduce your problem.


I have used the latest development version of Quantum ESPRESSO (QE) from Gitlab 
(downloaded on 8 February 2023). Also, I changed somewhat your input file to 
make it run faster and also I used norm-conserving fully-relativistic 
pseudopotentials from the PseudoDojo library (because I do not know which ones 
you used). Please try to reproduce my results using the latest development 
version of QE. Here are all the files:

https://drive.google.com/drive/folders/1vWriLf_IZge___Zs9Oh_eQsEECpwy7f7?usp=share_link


If this works, then try once again for your input file using the same 
development version of QE. Please note that there are some inaccuracies in the 
syntax in your input file, so please pay attention to this and fix it.


HTH

Indeed there seems to be a problem. We will investigate this issue and will 
come back to you ASAP.

Dear Mustafa,


> Is it possible to calculate DFT+U with noncollinear?


Yes


Currently, in Quantum ESPRESSO this is implemented in the framework of the 
Lichtenstein formulation.


Please provide all the input and output files (using public shared folders, 
e.g.Google Drive) that show the problem.
