[QE-users] Best Hubbard occupation on the fly

2024-01-08 Thread Mpayami via users
Dear QE Community, Hello. I am interested to know how can one find the best Hubbard occupations (or the best in a given model subspace ) in DFT+U on the fly? The question arises from the fact that in an AIMD run which the system stays on BO-PES, within a DFT+U an update to occupation matrices

Dear Elham, the static dielectric constant is computed by the phonon (ph.x) code in non-metallic crystals, just by setting epsil=.true. See for example, step 7 of example 1 therein (PHonon/examples/example01) If you want the electronic or phononic contribution to the complex

Dear Quantum ESPRESSO Users, I am currently working on a project that requires the calculation of the dielectric constant of a material, and I would like to use Quantum ESPRESSO for this purpose. I am reaching out to the community to ask for guidance on how to perform these calculations
