[QE-users] How to plot the |psi|^2 state for hole

2020-07-06 Thread Andrey Chibisov
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 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 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). Best Oleksandr On 06/07/2020 11:52, Michal Krompiec

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
