LF effects inclusion in yambo_kerr

Postby mferri » Fri Jun 24, 2016 2:43 pm

Dear developers,

sorry if it's not the right section. I would like to ask if it's possible to include local field effects in yambo_kerr.
I read the paper PRB 86, 125139 (2012) but i don't know how to do it in pratice.
I need LF effects because within the bare IP approximation I obtained huge kerr parameter Theta of the order of 10-20 degrees :? . I'm dealing with a 1D nanoribbon and I found that the inclusion of LF effects reduces considerably the absorption spectrum in the direction perpendicular to the ribbon (as in PRB 72, 153310 (2005)). I would like to see if it's the same for the off-diagonal components.

Cheers,

Matteo

Dear Matteo,
it is not possible with the GPL version.

I'll contact you in private for the non GPL version.

Best,

Dear Davide,

is it still not possible to include LF and electron-hole effects for calculation of Kerr parameters in the GPL version of yambo_4.2.0 ?

No unfortunately it is not.
Indeed the implementation is there, but we would like to test it before doing a release.
