Dear Experts

I'm working on PDOS for a system with four types of atoms, say A4B4X8Y4. I just change the following parameter in the PDOS calculation:

Code: Select all

% PDOS_kinds
-1 |-1 | # Select atom kind range
%

as

Code: Select all

% PDOS_kinds
1 |1 | # Select atom kind range
%

for A atom and 2 for B and so on.

For individual orbital contribution I am changing

Code: Select all

% PDOS_l
-1 |-1 | # Select angular momentum l range
%

as 0,1 for s and p respectively.

Is this procedure correct or not? And unlike QE, ypp will give the summation (for all the s/p contribution for 4A atoms) as output, right? or should I do for all the atoms and do the summation? Any response would be greatly appreciated.

Thanks and Regards

The procedure is correct.
Please notice that you need to run p2y after having computed the PDOS with the QE post-processing tool.
If the pdos database is found by p2y, it will then be converted and used by yambo/ypp.

I confirm that ypp will give only selected l values summed over m_l

Best,
D.

Dear Davide

Yes, noted. I followed the same. Thank you so much for your prompt response.
