Hello All,
I want to produce fat bands (orbital resolved) in NiO (LDA+U). I know the
calculations of fat bands, I already did in Si.
But the total band structure(a combination of all orbitals) that I m
getting in NiO is similar as I obtained bands from wannier bands
calculations. I am not able to
Thank you so much Paolo! That fixed my problem.

Dear altruist,
I used kpoints.x to generate the uniform k-point grids this time I didn't
get "Note: The following floating-point exceptions are signalling:
IEEE_DIVIDE_BY_ZERO" message for scf and nscf calculation but got it for
epsilon.x calculation and the real and imaginary parts of the
Hello,
I'm trying to run a GWL calculation on a small (8-atom) cell of a
semiconductor, with 10x10x10 k-point sampling. Following the tutorial
(and example05), I ran the pw.x scf calculation, then head.x, then a
gamma-only nscf calculation, then pw4gww.x.
When running pw4gww.x, I'm getting this
Dear Vivek,
Where did you get the pseudopotentials? I am asking this because with USPP
epsilon.x doesn’t work and with the NC PP that I used, I got divide by zero
error. Please it will be of great help if you let me know the source of the
PP.

Dear Vivek,
When I run epsilon.x, I received the following error message such as
'non unifrom kpt grid'. And I added nosym = .TRUE. and noinv = .TRUE. in
to my epsilon.x input file by reading other related threads but I got
an another error message such as 'reading namelist ENERGY_GRID'.
Dear QE users,
When I run epsilon.x, I received the following error message such as '*non
unifrom kpt grid'.* And I added nosym = .TRUE. and noinv = .TRUE. in to my
epsilon.x input file by reading other related threads but I got an another
error message such as '*reading namelist ENERGY_GRID'*.
Hi Pietro,
Thank you for taking the time to respond. This has been a very enlightening
discussion for me. I will try the Wannier code and see what I get.
Best wishes,
Vahid

Dear Iurii, dear Oscar
Thank you for your feedback. Ok, as a summary we need a full-time PhD
project or a very motivated post-doc but there is real hope that this
produces a very useful tool. Not the worst start...

Thanks! Many thanks! Super thanks for your patient and detailed answers, Paolo.
It finally got solved. Following your guidance, I will do more digging and
tests on these variables.
all best

I think that I could answer to the first question.
In linear response the exx integral are different respect with to ground
state calculation, because they contain the response wavefunction, so
you need three different ACE operators (without response wfc, with

Hi Vahid
In principle all occupied bands could contribute to the big difference
between the dynamical charges and the oxydation numbers. How much they
contribute depends on their polarizability. And I agree with you that
following what I said about the behavior of the S-3p band, the Pb-6s
