EPW Forum

Dear Lee, I tried to make it work by myself with changing flags. Finally, I figured out that "elph" must be true. I don't know why I should calculate e-phonon coefficient for e-plasmon self energy and spectra function calculation. I thought plasmon is only charge carrier related. But, when I changed ...

Dear Lee, Here is my updated input script, just same as before but "vme = 'dipole'" is included. ---------------------------------------------------------------------------- -- &inputepw prefix = 'tis2' outdir = './out/' elph = .false. !kmaps = .false. epbwrite = .false. epbread = .false. epwwrite ...

Dear Lee,

Sorry, I just added "vme='dipole'" in the previous input file and run the epw, but I could not get a spectra data.
And the output file is the same as without vme flag.

I wanted to calculate epw with specfun_pl =.true. and plselfen =.true., but the spectra didn't come out. When I calculate the epw with specfun_el =.true. and elselfen =.true., I could get "specfun.elself.20.000K" and "specfun_sup.elself.20.000K". But it didn't work with "pl" with same other inputs ...

I need to calculate the system with Hubbard U correction. So, I put the Hubbard code in scf file as below. lda_plus_u = .TRUE. lda_plus_u_kind = 0 Hubbard_U(1) = 3 Hubbard_U(2) = 0 Then I run ph.x with ph.in file with "fildvscf = 'dvscf'", because of later EPW calculation, like "dvscf_dir = './save ...
