Dear colleagues,I study hole states in B-doped silicon.How can I plot the |psi|^2 state for hole by means of 'lsign' command in pp.x?Or perhaps, is there another way? -- Best regards,Dr. Andrey Chibisov, Ph.D.Senior Researcher,Laboratory of Numerical Methods in Mathematical Physics,Computing
Dear Paolo,
I appreciate greatly your response as it directs me to the obvious mistake
that has cost me so much time.
Thank you so much Sir.

Dear respected QE users,
I have consistently have issues with open_grid.x code. Search on the
archive did not yield positive results.
The code crash consistently on the cluster machine and personal laptop. The
error message returned by the code is

Dear All
I tried to use QE to compute the work function for some metallic single wall
nanotubes. I studied the workfunction example provided by the QE code, and
searched in the QE user archives where I found some useful descriptions on the
calculation of work function, but I am still confused
Dear all,
I want to calculate the formation energy of silicon using quantum espresso
, can you tell me the procedure or things I have to learn .
With thanks,

Hello again,
I checked , and found the work of Tromach et al.,
https://doi.org/10.1039/C9CP02455G / .
Authors constructed D3 enhanced PAW potentials for some superheavy elements,
but only in VASP POTCAR format (see

Dear Singaravelan
nscf or band calculations must be strictly performed *after* scf
calculations, using the very same scf potential and calculating with
this potential the eigenvalues at whatever k-point, requiring less
computational resources than scf calculations. Intrinsically, there is
Dear all,
Let I am performing calculation for silicon.
I performed convergence test for no.of k points with the scf calculation
and found that no. of k points as 4 4 4 0 0 0.
*Question:For nscf calculation the no. of k points has to be doubled or not
?. That is: 8 8 8 0 0 0.*
For nscf calculation
Dear Neelam
Other than this, it would be useful if you could also show the in/output
files of your system. While it does not seem large the memory usage
depends on the atoms/pseudopotentials you are using, size of the vacuum
(if any).

Dear Neelam,
I am by no means an expert, but from my limited experience I can say that
4GB of RAM is not a lot, to put it mildly - but at the same time, your
system isn't large. In this case, I wouldn't use any parallelization on
k-points (pw.x -npool 1) and make use of symmetry as much as
Dear expert and all
I am making the supercell of 2x1x1 total 24 no of atoms, and perform scf
calculation .but there is memory related problem currently i am using 4gb
RAM.
What can i do to solve this problem?
Thanks in advance

Yes, this is the point. Integrations must be done to high energies, and this is
not expensive at all using turbo_spectrum.
