Quasiparticle width and lifetimes
Posted: Mon Jun 28, 2021 2:04 pm
Dear developers,
I found in the example 'electron-phonon coupling' of yambo wiki page, the last column of output o.qp is the width of the quasiparticle which is also can be transferred into lifetime. My question is what the difference of the lifetime here compared with the results from DFPT? (just the bare and the dressed particles or any others?)
Thanks!
