Dear wien2k users,<div><br></div><div>I have some confusion with regard to the DOS and band structure calculations when we consider spin-orbit coupling (SOC) in strongly correlated systems.</div><div>While perfoming the DOS calculation for spin-polarized case CONSIDERING SOC, I see the spin up and spin down panel with different features in DOS plot. </div>
<div>Is it really true as SOC mixes the up/spin DOS simultaneously so that we get the combined up/dn DOS. </div><div>But rather I see different feature in both up/dn channels. </div><div>Does it mean that the DOS of up/dn be truncated. </div>
<div>(I have seen several papers where spin-up and spin-down DOS considering SOC are plotted but I did not find any reasonable explanation.)</div><div><br></div><div>In the meantime, for bandstructure, I can have the similar bandstructure even for UP/DN. Using the following commands:</div>
<div><div>x lapw1 -band -up </div><div>x lapw1 -band -dn</div><div>x lapwso -up </div><div>x lapw2 -band -qtl -so -up</div><div>x lapw2 -band -qtl -so -dn</div><div>x spaghetti -up -so -p</div><div>x spaghetti -dn -so -p</div>
</div><div><br></div><div>I am interested to trucate the spinup/dn bands in bandstructure if DOS truncation is correct.</div><div><br></div><div>I will be glad for your kind response as SPIN-ORBIT COUPLING becomes excessively important when we discuss the electronic and magnetic properties of strongly correlated systems.</div>
