<div dir="ltr">Dear all,<div><br></div><div>I have a fairly general question: when calculating the angular momentum character of band structures the choice of pseudo seems to play an important role.</div><div><br></div><div>When comparing the angular momentum character of silver bands near the Fermi level I get from FLAPW mostly s and p character. Doing the same with PAW pp from the pslibrary I get results that are fairly consistent; using GBRV Ultrasoft ones the weight of the p orbital is greatly reduced and, when using norm-conserving PP the entire weight of the p orbital is "down-shifted" ~40 eV towards the core states.</div><div><br></div><div>In each case I carefully checked the output of projwfc and re-ordered the projected angular momentum states for plotband.x accordingly to the information given in the pseudo header; eg:</div><div><br></div><div><div> <PP_INPUTFILE></div><div># ATOM AND REFERENCE CONFIGURATION</div><div># atsym z nc nv iexc psfile</div><div> Ag 47.00 6 4 4 upf</div><div>#</div><div># n l f energy (Ha)</div><div> 1 0 2.00</div><div> 2 0 2.00</div><div> 2 1 6.00</div><div> 3 0 2.00</div><div> 3 1 6.00</div><div> 3 2 10.00</div><div><b> 4 0 2.00</b></div><div><b> 4 1 6.00</b></div><div><b> 5 0 2.00</b></div><div><b> 4 2 9.00</b></div></div><div><br></div><div>and</div><div><br></div><div><div> state # 1: atom 1 (Ag ), wfc 1 (l=0 m= 1)</div><div><b> state # 2: atom 1 (Ag ), wfc 2 (l=1 m= 1)</b></div><div><b> state # 3: atom 1 (Ag ), wfc 2 (l=1 m= 2)</b></div><div><b> state # 4: atom 1 (Ag ), wfc 2 (l=1 m= 3)</b></div><div> state # 5: atom 1 (Ag ), wfc 3 (l=2 m= 1)</div><div> state # 6: atom 1 (Ag ), wfc 3 (l=2 m= 2)</div><div> state # 7: atom 1 (Ag ), wfc 3 (l=2 m= 3)</div><div> state # 8: atom 1 (Ag ), wfc 3 (l=2 m= 4)</div><div> state # 9: atom 1 (Ag ), wfc 3 (l=2 m= 5)</div><div> state # 10: atom 1 (Ag ), wfc 4 (l=0 m= 1)</div></div><div><br></div><div>tells me that the 4p-character are the bold states (list of atomic wfc 2 3 4).</div><div><br></div><div>Is this a well-known "feature" of different pseudos or am I doing something else wrong...</div><div><br></div><div>Thanks in advance for your help!</div><div><br></div><div>Best,</div><div>Chris</div><div><br></div><div><br clear="all"><div><br></div>-- <br><div class="gmail_signature"><div dir="ltr">Postdoctoral Researcher<br>Center for Quantum Nanoscience, Institute for Basic Science<br>Ewha Womans University, Seoul, South Korea<blockquote type="cite" style="font-size:12.8px"><div dir="ltr"><div><div dir="ltr"></div></div></div></blockquote></div></div>
