Hello dear experts and users I try to execute the tutorial of the school of 2024 , Exercise 2 done in Wednesday dedicated for drift mobility the epw1.in is stopped at this stage. I think that is related to flikf and fliqf files defined in the tutorial file. Can someone help me to solve this error ...

Hello dear users and experts
I seek for using the carriers concentration of holes and electrons in order to have their effects on superconducting properties
can i use ncarrier in the calculation of superconducting gap.
best

Dear H.Lee yes you have reason i just figure out that i use a wrong process to get the phonon linewidth what i want is to plot the phonon self energy on the phonon dispersion of the system i use two inputs the first is for giving me the out put band.kpt and it's turn well epw.in -- &inputepw prefix ...

Dear H.Lee Thanks you for your quick reply here attached the inputs -- &inputepw prefix = 'B3S' amass(1) = 10.811 amass(2) = 32.065 outdir = './' iverbosity = 0 ep_coupling = .true. elph = .true. epbwrite = .true. epbread = .false. epwwrite = .true. epwread = .false. nbndsub = 12 wannierize = .true ...

Hello dear experts and users After getting the phonon stable and a good spread not exceeds 23 for 12 bands and all the physical values are normal i decide to plot the phonon linewidth but i got a discontinued lines and a wrong phonon dispersion not the same as the phonon in the save file. can ...

Hello dear experts and users
I saw in different articles the plot of the electron-phonon coupling strength on the fermi surface, there is any possibility to do it with epw, there is any file with cube extension can i plot i like what i do with fermi surface

Thanks a lot
best regard

Hello dear experts Thanks you for the reply, i use the 5.3.1 epw version All is good in wannierization and projections here attached the epw input -- &inputepw outdir = './' iverbosity = 2 ep_coupling = .true. elph = .true. epbwrite = .true. epbread = .false. epwwrite = .true. epwread = .false ...

Hi dear users and experts well i had a several problems when i calculate the anisotropic superconducting gap in the first calculation i had 9 K° in the critical temperature and now is totally different also the calculation need some memory and i have 32go which is fair enough for it can someone help ...

Hello Sir hari I'm sorry for the late reply i got a technical problem in the hardware on my PC i just solve it well in the error above i think that i don't have space in the hard disk now i turn in another PC This is the whole output i dont know if i should restart all the calculations ``:oss/ `.+s ...

Hello dear hari well i did all the commands and i had an error till i change wannierize from true to false and i add kmaps = true the calculation turns for each cordinate till i get this error %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Error in routine write ...
