Dear M.Veithen, X.Gonze and Ph.Ghosez;

 

    In your presentation you demonstrated us how to calculate nonlinear optical susceptibilities and first order derivatives of linear optical susceptibilities. Here I have some questions about these matters:

    1, like optical susceptibilities, nonlinear susceptibilities are of course frequency dependent. Then can abinit calculate the frequency dependent susceptibilities?

    2, I find examples such as Tese_v4/T54.in. the output gives a nonlinear optical susceptibilities matrix, does this give the kappa（nonlear suspceptibilities ）at infinite frequency or at zero frequency?

    3, any publications related to this topic? Or with examples?

 

    Regards
