QE 6.1 and 5.1 yield completely different pdos for a simple CO molecule. The results from QE 5.1 are completely wrong, because 2px and 2py associated with 1pi orbitals should not be splitted into three levels. These outcomes are impossible for DFT calculations. The results from QE 6.1 is also unsatisfying;the 2pz states should not be populated at a deep level below -28 eV? </div><div><br></div><div>Best</div><div><br></div><div>Jibiao Li</div><div><br></div><div>Yangtze Normal Univeristy, China</div><div><br></div><div>CO.pw.inp</div><div><br></div><div> &CONTROL</div><div> calculation = 'scf' ,</div><div> restart_mode = 'from_scratch' ,</div><div> outdir = '/home/jibiao/Calc/CO_Fe100/T/' ,</div><div> pseudo_dir = '/home/jibiao/Codes/pseudo/' ,</div><div> prefix = 'CO' ,</div><div> tstress = .true. ,</div><div> tprnfor = .true. ,</div><div> /</div><div> &SYSTEM</div><div> ibrav = 6,</div><div> celldm(1) = 10.847032278,</div><div> celldm(3) = 3.28,</div><div> nat = 2,</div><div> ntyp = 2,</div><div> ecutwfc = 29 ,</div><div> ecutrho = 180 ,</div><div> occupations = 'smearing' ,</div><div> degauss = 0.05D0 ,</div><div> smearing = 'methfessel-paxton' ,</div><div> exxdiv_treatment = 'gygi-baldereschi' ,</div><div> /</div><div> &ELECTRONS</div><div> mixing_beta = 0.2D0 ,</div><div> diagonalization = 'david' ,</div><div> /</div><div>ATOMIC_SPECIES</div><div> C 12.01000 C.pbe-van_ak.UPF </div><div> O 15.99900 O.pbe-van_ak.UPF </div><div>ATOMIC_POSITIONS angstrom </div><div> C 2.870000002 2.869999976 7.634009081 </div><div> O 2.870000022 2.869999989 8.812254230 </div><div>K_POINTS automatic </div><div> 4 4 1 0 0 0 </div></div><div><br></div><div>CO.projwfc.in</div><div><br></div><div><div> &PROJWFC</div><div> prefix = 'CO' ,</div><div> outdir = '/home/jibiao/Calc/CO_Fe100/T/' ,</div><div> ngauss = 0 ,</div><div> degauss = 0.01470 ,</div><div> DeltaE = 0.02 ,</div><div> /</div></div><div><br></div><div><br></div></div></div>_______________________________________________<br>Pw_forum mailing list<br><a href="mailto:Pw_forum@pwscf.org">Pw_forum@pwscf.org</a><br>http://pwscf.org/mailman/listinfo/pw_forum</blockquote></div><br></div></body></html>
