p2y error with Hybrid

Concerns any physical issues arising during the setup step (-i option). This includes problems with symmetries, k/q-point sets, and so on. For technical problems (running in parallel, etc), refer to the Technical forum.

p2y error with Hybrid

Post by marco.c » Mon Jan 25, 2021 3:43 pm

Dear Developers,

I am trying to do some gw computations in 1D systems. Just for comparison, I decided to start from two different DFT calculations (PBE and PBE0) performed with QE 6.6.

p2y works properly in the case of PBE calculation, while it fails for the hybrid wave function (I'm using yambo 4.5). The two input files are exactly the same except in the part where I define the paramter for the hybrid functional.

I have listed the error message as below. Could you please tell me how to fix this problem?

Thank you in advance,

M

Dear Marco,
can you please sign your post with your name and affiliation? This is a rule of the forum and you can do it once for all filling the signature in the user profile.

The error is due a change of format in the QE output with respect previous version, the new release of Yambo (5.0) should be compatible:
You can download it from:

Code: Select all

git clone git@github.com:yambo-code/yambo.git
If the problem persist, please send us your QE input and we will try to reproduce the problem.

Best,
Daniele

Dear Daniele,

first of all, thank you very much for your prompt reply.

I'm very sorry about the sign, now I've added it.

With Yambo5.0 p2y works properly.

Thank you again for all.
