Hi,

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

 ![Screenshot from 2024-01-09 01-44-33](https://global.discourse-cdn.com/free1/uploads/itensor/original/1X/39ab5d80d12528ee27bba7c43916b9d60dad79b7.png)

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

It will help many of us here.

With Regards.
