el-ph matrix elements in complex form

Running EPW
1

Dear Experts,

I want to use el-ph matrix elements generated from EPW, which are stored in absolute numbers (|g|) and not in general complex form. Is there any way I can find the actual complex numbers for g^ij_v? The data I get currently from EPW is the following. (The last column is a modulus of g.)

   Electron-phonon vertex |g| (meV)

     iq =       1 coord.:    0.0000000   0.0000000   0.0000000
     ik =       1 coord.:   -0.5000000  -0.5000000   0.0000000
      ibnd     jbnd     imode   enk[eV]    enk+q[eV]  omega(q)[meV]   |g|[meV]
     ------------------------------------------------------------------------------
        1        1        1     -6.7177     -6.7177       -0.0135798814    0.0000000000E+00

Any suggestion or help will be really helpful.
Thank you very much.

Dear all,

I just found out that this routine printing.f90 has been updated in the latest version. And I can get the complex number from there.

Thank you very much.

Sincerely,

Hi,

Please use V6.0 of EPW (with QE 7.5). This new version outputs the real, imaginary, and the absolute el-ph matrix elements.

Best,
Sabya.
