Difference-frequency generation (DFG)

Post by sabrine » Tue Jul 25, 2023 6:52 pm

Dear Yambo develloper and user,

I am using yambo Version 5.1.0 Revision 21608 Hash.

I need to calculate the Difference-frequency generation (DFG). Is there are a way to do such calculation using yambo ?

Thanks

Best.

Dear Sabrine

in principle you can calculate DFG with Yambo, but did not write a tool to analyze the results

It is sufficient that you put two laser fields in input by doing

Code: Select all

yambo -u p
and then it will produce the correct polarization in output.

You can Fourier transform it and analyze it
