Thanks you Mr ponc

this is the line-width out put as you see i had a huge line-width # Electron lifetime (meV) # ik ibnd E(ibnd) Im(Sgima)(meV) 1 1 -0.77978892264099E-03 0.94597177895615E+03 1 2 0.36042546184438E+01 0.90572584063543E+03 1 3 0.77415380240782E+01 0.96141149409943E+03 1 4 0.15943686353390E+02 0.112433435...

Well i didn't arrive to send the input in private so i share it here this is the input in order to have the linewidth and the eliashberg spectral function -- &inputepw prefix = 'XX' amass(1) = XXXXXXXXX outdir = './' iverbosity = 1 ! ep_coupling = .true. elph = .true. epbwrite = .true. epbread =...

Hi concerning the dimension of lambda is a dimensionless parameter which describe the enhancement of the band mass it should be around 0.5 and 2 for the Eliashberg spectral function is measured by meV like the frequency of phonon its shouldn't have more than 2 meV For the professor Roxana i sent to ...

Hi all i had unreasonable value of lambda and eliashberg spectral function Eliashberg Spectral Function in the Migdal Approximation =================================================================== lambda : 1757.8157878 lambda_tr : 1946.0595019 Estimated Allen-Dynes Tc logavg = 0.0000886 l_a2F = 1...

Hi guys As you know bye the topic i get some unreasonable values of the linewidth and the spectral function of eliashberg and also the electron phonon coupling strength i have many suspects before but now i get the phonon dispersion like the litterature and also the band structure conserning the epw...

hello
i work on tutorial about the superconcting gap of mgb2 and i got the result file on cube form now i want to plot the result and i don't know the process to get the cubic form

hello mr Hari Paudyal
i d'ont use this command on my calculations and i got got this unreasonable lambda value it's should be in the order of some meV and i got it in the order of eV this mean more than 1000 times more than the normal case
best regards

Hello everybody
i work on superconducting properties of an material 2D i run epw in order to have the electron phonon coupling and i found a huge lambda
lambda = 7456 meV
