<DIV>Dear all,</DIV>
<DIV>Does anyone know that when I added spin to the system, whether it costs much more </DIV>
<DIV>time to calculate the phonon dispersion relation ?</DIV>
<DIV>Whether there are parameters to improve the efficiency of calculating the phonon dispersion relation ?</DIV>
<DIV> </DIV>
<DIV>Regards,</DIV>
