[Pw_forum] how can I plot phonon dispersion and the a2F(omega) vs. omega function curve?

[Eyvaz Isaev]

Hi,

To plot phonon dispersion relations use PlotPhon utility (see your QE 4.2 case).
You can gain more info from your phonon calculations if you look at also QHA 
directory.

Subject: [Pw_forum] how can I plot phonon dispersion and the a2F(omega) vs.

Dear sir,

I want to calulate phonon properties, including  phonon dispersion, dos, el-ph 
coupling, and a2F(omega), 

now I have 4 questions (the version I used is 4.04):

1. What is the meaning of the files named a2F.dos.1,..., a2Fdos.10?

2. What is the meaning of the files named a2Fmatdyn51,...,matdyn60?

3. how can I plot phonon dispersion using the file of case.freq?

4. which file can be used to plot a2F(omega) vs. omega function curve and how to 

plot it?


Thanks for any reply!

Best wishes!
