Dear kwant users, I find the wavefunction methods with sufficient example for calculation of local observables using operators in kwant. I would also like to calculate the local observables using Green functions.
As far as I know, I understood that the green_function method only provides the surface Green function at the interface of the lead and the scattering system which is helpful to calculate the total conductance. How can we define local observables using Green functions in kwant? Is there any methods like operators included in the kwant? Thank you Hari
