[QE-users] Pseudopotential nomenclature: n vs nl

[Pietro Davide Delugas]

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

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
