Dear Gyanu, Thank you for your answer. If I run "phononselfen=.true.", I get a lambda.phself file at 300 K. Is the electron-phonon coupling constant depend on temperature? The reason I am asking is that in the superconducting calculation, we use the same electron-phonon matrix element at different t...

Dear all,

Is it possible to get information about the electron-phonon coupling strength
for a particular phonon band for a set of selected q points?

Please let me know how if this is possible.

With regards,

Dear all, I am calculating the superconducting properties of some systems. In the output, the T_c value is around 9 K and the BCS gap is 1.43 meV. Now, If I solve the isotropic Eliashberg equation at temperature 9.5 K I am getting superconducting gaps around 2.4 meV. Is this possible? Is this mean t...

Dear all, I am running the MgB2 example as given in the examples. In the epw part, the code started running, and after some time, it stuck at some point without quitting the job. However, it is running successfully in serial. I installed the qe-7.2 using intel one API. I have attached the necessary ...
