How to set different third-order processes

Post by lyzhao » Sun Apr 12, 2020 8:43 am

Dear all,
Could you tell me how to set frequencies for different third-order processes in yambo_nl?
for example, X(w:w,-w,w), X(3w:w,w,w)

Best regards,

Dear Youzhao Lan

at present, the code can only calculate third-harmonic generation,
you set a laser field at frequency w and calculate the response a 3w.
In the new version we will introduce more possibilities

You can have a look to this tutorial
