Thank you Pietro. I guess you mean one there is one more Kleinman-Bylander (KB)
projector in the -n- pseudopotential.
Can you kindly give a little more description, so that it will be helpful for
me as I am not having a Quantum Mechanics background..
Regards,
Krishnendu

... plus one more KB projector for the 3D channel.

Subject: Re: [QE-users] Pseudopotential nomenclature: n vs nl
Hello
I don't know exactly; I guess the l stands for low (slightly lower accuracy but
more efficient). In any case, in the ps library, all pseudos with the nl label
belong to the low collection. The difference is in the inside 🙂 , one uses
shorter cutoff radii and can use a smaller ecutrho.
Hope this helps
Pietro

Subject: [QE-users] Pseudopotential nomenclature: n vs nl
Hello,
Can you kindly let me know the diffternce between the pseudopotentials,
Al.pbe-n-rrkjus_psl.1.0.0.UPF<
https://pseudopotentials.quantum-espresso.org/upf_files/Al.pbe-n-rrkjus_psl.1.0.0.UPF
> vs. Al.pbe-nl-rrkjus_psl.1.0.0.UPF<
https://pseudopotentials.quantum-espresso.org/upf_files/Al.pbe-nl-rrkjus_psl.1.0.0.UPF
>
that is one has nl vs. the other one has n
Thank you,
Regards,
Krishnendu
