Yambo Community Forum

Dear all,

I have viewed the code at https://github.com/yambo-code/yambo/blo ... _current.F. The calculation here is for the total real-time current. If we want to obtain the shift current, do we need to perform post-processing using yambopy, including Fourier transformation, frequency selection, etc.? Could you provide an example tutorial on how to calculate the exciton shift current?

Best,
sunxl

Dear sunxl

for the Shit Current pluse use Lumen that is a fork of Yambo that you can find here:
https://www.lumen-code.org/

you can find tutorial on shift current here:
https://www.lumen-code.org/wiki/index.p ... ft_current

please use the last version of YamboPY for postprocessing.
let me know if it works
best
Claudio
