Hi, everybody.
In the version 4.3.2 of Quantum espresso, the lambda.x reads the files
"filelph" produced by phonon calculations to get the electron-phonon
coefficient (lambda) , wlog and superconducting temperature (Tc). So only
a course q grid used in the phonon calculations is summed over in the
lambda.x. I found in some systems the lambda obtained from lambda.x is
quite different from the value got form matdyn.x, which is based on a dense
q grid. In this respect, are the wlog, Tc got from lambda.x reasonable?
If not, how can I obtain reasonable wlog?
Thanks.
Any help will be appreciated.
