Re: electron-phonon matrix elements

Dear Samual, Thank you for the reply! I tried to modify the output writing part of the program (subroutine elphsum2 of elphon.f90) and performed some calculations. I have tried different q-points q1 0.000000000000000 0.000000000000000 0.000000000000000 q2 0.000000000000000 0.000000000000000 0 ...

Phonon frequencies and irreducible representations

Dear All, I am trying to compute the electron-phonon coupling matrix for an 8 atom cell using ph.x with k-grid of 12x12x6 and q-point 4x4x2. I am computing each of the 12 q-points separately. For the first q-point (gamma-point), the system has 16 irreps. From the output file one can get all the mode ...
