>difficult to converge, especially with respect to the cell size.<br><br>Sir Paulatto,<br>Thank you very much for your invaluable help. I got to understand that it is to do with transferability of pseudopotentials, but sir i would like to ask one last question regarding this occupations issue. <br>
Suppose i have a single Mn atom in a GaAs supercell. The hole(spin dw) associated with Mn sits in one of the Mn d states (as i inferred from spin resolved local moments on Mn atom (~5up + ~1dw )). I want to delocalize the hole by setting the d spindown occupations to ~zero. <br>
is there a way to specify this as i dont know the band number of hole apriorily<br><br>sincerely<br>-- <br>Sreekar Guddeti<br>BTech + MTech<br>IIT Bombay<br>India<br>
