Dear Developers,

I would like to be able to extract the four spinor components of an exciton wavefunction in a system with spin-orbit coupling, and the spatial wavefunction component associated with each spinor. I was wondering if there is a method of extracting this information from the BSE output, please?

Many thanks for your help - much appreciated.

All the best,

Will

Dear Will,

the spinor components in the excitonic wavefunctions are summed up.
If you want to look at each component you need to slightly modify the source:

in ypp/excitons/excitons_WFs.F
you will find:
and you can comment the first or second line for the first and second spinor components respectively.

Best,
Daniele

Dear Daniele,

That's really helpful, thank you very much.

All the best,
