EPW Forum

Dear developers From previous discussion (https://forum.epw-code.org/viewtopic.php?p=4574&hilit=Hubbard#p4574) I learned that EPW may not be able to deal with DFPT+U system, even if DFPT+U does output dvscf file According to https://journals.aps.org/prl/pdf/10.1103/PhysRevLett.127.126404, in DFPT+U ...

I am quite interested in complex value of electron-phonon matrix in order to do exciton-phonon interactions.I have read your discussion about it. As far as I know, EPW use wannier interpoltation to interpolate dvscf and wavefunction on a finer mesh ,then use them to construct electron-phonon matrix ...

As far as I know, EPW use wannier interpoltation to interpolate dvscf and wavefunction on a finer mesh ,then use them to construct electron-phonon matrix. However wannier interplotation is known to bring some gauge problems. My question is : if I properly modify the ''print_gkk in printing.f90 ...

I want to calculate electron-phonon matrix using EPW in bloch basis, I have noticed using input 'prtgkk' EPW can print the absolute value of electron-phonon matrix. What should I do ,if I want a complex value of electron-phonon matrix? (Maybe some scripts need to be modified?) .I found print_gkk(iq ...
