Yet it is possible. You need a very goo representation of the Fermi surface in order to identify the possible el-ph processes, but such a fine grid is not required to have good phonons.
Also note that there are at least two QE packages to do el-ph calculation with Wannier interpolation : epik by M Calandra and EPW by F Giustino regards -- Lorenzo Paulatto - Paris On Dec 6 2021, at 3:27 am, Elio Physics <[email protected]> wrote: > > Dear all, > > As is well known in electron-phonon calculations, one has to do a self > consistent (scf) calculation over a dense electronic grid followed by an scf > calculation on a coarse grid. > The electron phonon calculation is usually performed after calculation the > vibrational frequencies for each point. > > My question is : If we increase the dense grid, Is it possible (Is there a > way in QE) to compute the el-ph coefficients without recomputing the > dynamical files (vibrational frequencies), which actually depend on the > coarse grid.
