lifetime in spinpolarized calculations

Post by samaneh » Thu Sep 24, 2015 7:41 pm

Dear developers
I run yambo -g n -p p for a spin polarized system
but I do not know why all the data "Width[fs]" are positive for both spin up and down?
while in nonspin polarized calculations we have positive and negative data?!!!1
Thank you in advance

Dear Ataei,
not sure I understand what you mean.

I just did a quick test and with n_spin=1 and with n_spin=2 (case n_sp_pol=2, n_spinor=1).
I always get both positive and negative lifetimes.

Can you upload or attach to the message the results for the two cases ?
Also which version of yambo are you using ?

Kind regards,
D.
