<p> Hi, everybody.</p><p> 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?</p>
<p> Thanks.</p><p> Any help will be appreciated.</p>
