Exciton wave function superposition
Posted: Sun Jul 09, 2023 11:15 am
Dear all,
I'm using "ypp -e w" to plot the exciton wavefunction for a given K point after a finished gw-BSE result. If K and -K are equivalent points, is the output exciton function the result of superposition of these equivalent K-points exciton functions? Or is it that only one K point is considered, and the phase superposition of these equivalent K points is not considered ?
Best Regards,
