Dynamical structure factors for a 1D spin chain

[Explorer]

Hi,

I am very much interested in calculating the dynamical structure factors, as in attached figure, for a 1D spin chain systems.

Could you please share sample code/demonstration, for computing the dynamical structure factor.

It will help many of us here.

With Regards.

hello,I am interested in this problem too but I could not solve it. Could you please tell me where is the figure from? Thank you!
