quasi particle lifetimes

[dav78]

Hello,
I've installed the parallel yambo on my workstation successfully. I mean I can run all the examples with any problems or errors. Troubles arise when I try to make a G0W0 quasiparticle lifetime on my systems. Indeed, for some reason, when I try to generate the input using -l option, yambo simply produces an empty file.
On the other hand, as written above,m I can run this type of calculation with no problem on Solid_Al example.
I can't figure out where I'm wrong.
I'm not sure if it can be helpful but I've attached the r_setup generated after yambo initialisation.
hany clues or advise?

Cheers

Dear Dav78,
please fill your signature with your full name and affiliation, this is a rule of the forum.
The syntax to generate input files has changed moving from yambo 3.3 to 3.4 Check what release of yambo you are using and see the corresponding syntax
in the website. In this days I, and most of the developers, are out of office, if you are not able to solve the problem, please post it again and we will have a look to it
when coming back at office.
Best,
Daniele

Dear Daniele,
thanks for answering.

Being August (and being italian) I immagine that. I hope you are enjoying your deserved holidays

I am using the trunk devel version yambo 3.4.0 rev.2132

and see the corresponding syntax in the website.

Unfortunately I've been missing something more subtle that a syntax error I am afraid.
Indeed, not only yambo -H give me

-l :GoWo Quasiparticle lifetimes

but moreimporatnt it produces a correct input if I run it within the website example:" Beyond the Plasmon-Pole approximation: real-axis GW and lifetimes", producing nothing when I try to run on my system

Dear Davide,
having a look to your report, I realized you are dealing with a spin resolved system.
Actually, the lifetime runlevel has been never tested in this case. Davide, who coded most of the part of the spin-resolved case, told me that likely the lifetime calculation can work but again, it has never tested. You can remove the barrier substituting line 145 in src/interface/barriers.F

Code: Select all

on_runlevels='optics chi bse bsk bss em1s em1d ppa HF_and_locXC cohsex gw0'

with

Code: Select all

 on_runlevels='optics chi bse bsk bss em1s em1d life ppa HF_and_locXC cohsex gw0'

and test it by calculating the lifetime for a non-magnetic system using n_sp_pol=2 and verify that the code gives the same result of the n_sp_pol=1 case.
Not sure it will wotk, use at your own risk. If you manage to do that, please report the outcome.

Best,

Daniele
