[Pw_forum] LDA+U+Phonons in QE 5.3.0

2016-01-16 Thread W2AGZ
I just had a quick look at the source code, phq.readin.f90 in QE release 5.3.0, and see that support of lda_plus_u is still not supported for the calculation of electron-phonon interactions in Hubbard manifolds. It's been a number of years since this issue was originally posted on pw_forum. Is

Dear, Iurii Timrov I have tried using QE-5.5.0 for both SCF and TDDFPT But i recieived similar kind of error in lanczos.x output i.e. "mpirun noticed that process rank 1 with PID 1046 on node ermdc06 exited on signal 11 (Segmentation fault)". Cant find a way out of it? SAJID ALI

Dear all, I was run molecular dynamics with the car-Parrinello (cp.x). First I did the relaxation of the electronic wavefunction ( I don't know if it necessary to do it, because I get the positions from previous ab initio calculation). Second I did the relaxation of ionic coordinates ( an electon

Dear Andrey, You seem to run a super-cell, ie many cells along the 2D plane: Thus your band structure gets folded into the small Brillouin zone, and it is difficult to find the bands ("Dirac point") as-is. There are references now in the literature for un-folding the band structure, I know

Dear Sajid Ali, Why do you use now QE-5.2.1? Before you used QE-5.2.0. First of all, you should stick to one version, otherwise it is not possible to solve the problem. I suggest to use the latest official release, i.e. QE-5.3.0. On 2016-01-16 00:09, Sajid Ali wrote: > Dear, > Iurii
