TD-aGW shg oscillation

Post by Sunxl »

Dear developers,

I calculated the shg components xxx and yxx of TD-aGW according to this tutorialhttps://www.lumen-code.org/wiki/index.php?title ... or_TD-BSE). Finally, I obtained a shg spectrum with intense oscillations. Did I make a mistake in any of my settings? The attachment contains all my input and output files.

Best,

Dear sunxl,
I'm not sure what you are asking.

You followed the tutorial, and you got results for X2_yyy in hBN monolayer different from the ones reported in the wiki ?

Dear Davide,

Sorry, perhaps I didn't express myself clearly. My problem is that after I calculated the yxx and xxx components of SHG according to the tutorial, when I squared the real and imaginary parts and then took the modulus value, the resulting spectral line oscillated wildly, as shown in the following figure.
