Post unreasonable electron phonon coupling
Hi all
i had unreasonable value of lambda and eliashberg spectral function
Code:
Eliashberg Spectral Function in the Migdal Approximation
     ===================================================================

     lambda : 1757.8157878
     lambda_tr : 1946.0595019

     Estimated Allen-Dynes Tc

     logavg =    0.0000886 l_a2F = 1751.7988942
     mu =   0.10 Tc =         3.845000374466 K
     mu =   0.12 Tc =         3.788219159782 K
     mu =   0.14 Tc =         3.730767272617 K
     mu =   0.16 Tc =         3.672639590491 K
     mu =   0.18 Tc =         3.613831415621 K
     mu =   0.20 Tc =         3.554338527754 K

Hi,

It would be easy to go through your problem if you provide inputs/outputs of your system? Also, please include which version of the code and what parameters (for eg. k/q meshes) are you using. Someone will definitely help you after.

Best,
