Dear all respected PWscf users,
Greeting! I am new pwscf user. I use QE 6.1 to calculate electron phonon coupling constant. Many papers using pwscf included frequency dependent e-ph constant (please see the attached image). But I did not find any option in pwscf and searched many days in internet, eventually failed. I have also try to perform the integration lambd=2 int (a2F(w)/w dw) in mapple, but I got wrong results. I am not an expert in programming and scripting. Please can you help me in this regard. It will be highly appreciated.
Thank you!
Hi Alexandru Bogdan Georgescu!
Do you read my question? I already said that I use QE 6.1 (means pw.x and ph.x) to calculate Tc. In QE, there is no option to do this task. Thus, I have asked to experts who can help me to perform the integration manually! Thank you for your irrelevant answer!
Best Wishes!
Hello Dear Enamul
I have the same problem like you.
Could you plot lambda in terms of frequencies?
I am wondering if you could help me with this.
Best Regards
Vhaid
Dear all, there is an example in qe tutorials using aluminium about the e-p coupling. I suggest you to find that.
Hi Nulakani,
First you should understand my question. Sorry to say that. These tutorials will never tell you how to calculate frequency dependent e-ph constant.
Best Regards,
I strongly believe that RG is a forum for sharing knowledge. If everyone is a expert, then there is no need for you to ask this question. Either me or "Alexandru Bogdan Georgescu" suggested as per our knowledge for your question. But it is not good to you or for your research carrier to respond in such a way for either of these posts.
How do you feel if we answer this question like "how shame that dont you know answer for this question"
You can see many experts like Behnam Farid
posts, in which they are answering for every basic/hard questions (even though the questions are fundamentally wrong) to enrich the knowledge of users with out any harsh words or supremacyFirst you should understand/learn how to respond to an answer.
Best Regards
Hi Nulakani,
Thank you for your advice. If you think that I have said something wrong, I have already said that I am sorry for this. However, I think it is not good idea to answer a question without understanding it. If you have no money, then you would not try to give it to someone or help other. Hope you understand.
Best Wishes for you.
