[QE-users] integrated electron phonon coupling and superconducting gap

[Elio Physics]

Dear all,

I have two questions regarding the electron-phonon calculations in QE:

1- How to manually obtain the integrated electron phonon coupling lambda(w) in QE?  What i tried to do is  to compute 2* a2F(w)/w and summed these terms up to the value at which, lambda(w) is computed: for instance if  I want lambda(w) at w=w0, then I would sum all lambda(w) up to w=w0. Is this correct? If not, how can I obtain it?

2- Is it possible to obtain the superconducting gap from QE? If not, is there any other code that can be interfaced with QE and which uses the already obtained results from QE to determine the superconducting gap?

Thanks in advance.
