Dear QE users, I am going to calculate the spatial dependency of the wave function from the output HDF5 files from QE (for one specific k-point, such as Gamma). I know that the number 'evc' should be twice the 'Miller Indices' because it includes real and imaginary coefficients in the wave function: psi = sigma (C_real + i C_imag) * exp(iG.r). Everything looks fine, and I can calculate the wave function in a normal DFT calculation (I mean without spin-orbit coupling!!). But, when I use spin-orbit coupling, the number of 'evc' in the final .hdf5 file becomes four times the 'Miller Indices.' For instance, if I have 100 'Miller Indices, ' I will have 400 'evc' which is a bit confusing. Does anybody know how we can interpret it? Thank you for your suggestions.
Kind regards, Alireza Shabani Postdoc researcher, Denmark Technical University Copenhagen, Denmark
