[Pw_forum] How to understand the outcome of d3.x

[昶棘汐]

Dear all

I want to calculate the phonon lifetime by QE.  I have read some replays
about this question in this forum , and the thesis "Anharmonic Phonon
Lifetime in Semiconductors from Density-Functional Perturbation Theory" .
However I have not  understand how to use the outcome of d3.x . Actually  no
ideas about what the d3.x  calculate .  And  I can't find an answer about
this question in the forum .

Please forgive my ignorance . And I hope someone could tell me  it is not a
joke that QE can give us the outcome about phonon lifetime .

Thanks in advance . And best wishes .
