The PP were generated using (scalar) relativistic reference calculations. The basis sets are valence only and don't require relativistic corrections. regards JH ________________________________________ From: <a href="mailto:cp2k@googlegroups.com" target="_blank">cp2k@googlegroups.com</a> <<a href="mailto:cp2k@googlegroups.com" target="_blank">cp2k@googlegroups.com</a>> on behalf of xuan Garrett <<a href="mailto:xw97259@gmail.com" target="_blank">xw97259@gmail.com</a>> Sent: Wednesday, December 18, 2024 6:31 AM To: <a href="mailto:cp2k@googlegroups.com" target="_blank">cp2k@googlegroups.com</a> Subject: Re: [CP2K:20977] Re: For DFT calculation of metallic system Dear Frederick, Now my calculation for lanthanide, typically, available basis set files are BASIS_MOLOPT_UCL, BASIS_MOLOPT_LnPP1, and BASIS_MOLOPT_LnPP2. I have checked the latter two original articles, that they are 4f-in-core basis set with scalar relativistic effect included. While for BASIS_MOLOPT_UCL, the basis set of lanthanide series possesses 4f-in-valence property, where their qX(X for valence electron numbers) are larger than in BASIS_MOLOPT_LnPP2. And, I do not know if BASIS_MOLOPT_UCL is generated with the including of scalar relativistic effect. Or, if you have more suggestions about choosing basis sets for lanthanide elements in terms of basis set and potential. Thank you very much.

I am sorry for my not careful reading of this HOW TO manu. Now, I understand the meaning of this ENERGY. BTW, I am wondering if CP2K will treat this warning of spin_comtamination of kpoints in next released versions? Thank you so much.

Regarding our extrapolation question, have you already considered this HOW TO: <a href="https://www.cp2k.org/howto:static_calculation" rel="noreferrer" target="_blank">https://www.cp2k.org/howto:static_calculation</a> ? Best regards, Frederick xuan Garrett schrieb am Sonntag, 15. Dezember 2024 um 12:39:01 UTC+1: Dear cp2k, I am now testing the bulk Cu metallic system. During DFT calculation based on GPW, I switch on the UKS T and the FERMI_DIRAC smearing for calculation, along with the MONKHORST_PACK grids. Now, in my cp2k out file, I find the warning that : *** WARNING in qs_scf_post_gpw.F:1850 :: Spin contamination estimate not *** *** implemented for k-points. *** So, I am wondering if this warning will lead the error in the final energy. Since the metallic uses the smearing based on FERMI_DIRAC, the electronic entropy is induced. So if it means that the final term of Total FORCE_EVAL ( QS ) energy does not include the correction for electronic entropy term (T → 0) , the used ELECTRONIC_TEMPERATURE is 300 K. That is, the actual extrapolated ENERGY should be Total FORCE_EVAL ( QS ) energy - T*S_ele? Attached is the inp and out file.
