Dear all,<br>I use the version 2.1.5 of pwscf. When I calculate the electron-phonon coupling constant of the LiH. I calculate 47 k points in the IBZ.The output file lambda.dat is like this:<br># degauss lambda int alpha2F <log w> N(Ef)<br> 0.010 0.519654 0.000000 94.413 0.949231<br> 0.020 0.481122 0.000000 94.412 0.886274<br> 0.030 0.470335 0.000000 94.412 0.880906<br> 0.040 0.458617 0.000000 94.413 0.857064<br> 0.050 0.430279 0.000000 94.415 0.810680<br> 0.060 0.431049 0.000000 94.416 0.811986<br> 0.070 0.475063 0.000000 94.415 0.877232<br> 0.080 0.526288 0.000000 94.412 0.958069<br> 0.090 0.563168 0.000000 94.410 1.022181<br> 0.100 0.581296 0.000000 94.409 1.062365<br><br>We kown that . My question is why the lambda has some value while the int alpha2F are totally zero.<br>Any comments will be appreciated.<br>Best regards.<br><br><!-- footer --><br><br><br><br><br><div style="border-bottom:1px solid #999"></div><br>
