[QE-users] Fat bands production in NiO(LDA+U)

2020-04-16 Thread Poonam Kaushik
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

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. On Thursday, April 16, 2020, Vivek Christhunathan

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 Giuseppe, 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 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
