Converged parameters in tgw2 tutorial

The GW2 tutourial mentioned that if parameters in Bruneval[2006] is used, the G0W0 band width should be 10.54eV. I tried to modified tgw2_x series input files and obtain this value, but my result is ( New Fermi 7.179047eV - Gamma point lowest energy -2.737eV) 9.92eV , which is different from 10.54eV...

Re: How to use analytical continuation in GW?

Just to make sure, we are talking about analytical continuation of Sigma to the complex plane, as in the example v67mbpt/t02.in, and not analytical continuation of the screening, for a contour deformation G0W0 calculation, as in example "v5/t71.in". Indeed, in the example, a plasmon-pole ...

Re: How to use analytical continuation in GW?

What do you mean, "when you try to combine them" ? The proper way of doing it is to compute the screening in one dataset, and Sigma in the next one. Like in "tests/v67mbpt/Input/t02.in". This is as "combined" as it gets! Post your input if that doesn't help. Thank you ...

How to use analytical continuation in GW? [Edit:Bug Found]]

Hello, I am using abinit 7.2.1. From literature it said analytical continuation is implented in abinit, but I cannot find how to use it. In test v67mbpt, only seperated screen and Sigma calculations are found. When I try to combine them, it prompts error "Frequencies in the SCR file are not com...
