thank you for the fast answer, that sounds very helpful! Just a small question. The documentation tells me that the eigenvalues have to be integer and the order determines the order of blocks. Is the exact value of the eigenvalues of any importance?

Hi Daniel, Khani,
If you want to use multiple degrees of freedom in the leads, specify a conservation law with the matrix that has different eigenvalues for each combination of the quantities of interest. For example, if your sites have 4 orbitals, like Khani describes, you can specify syst = kwant.Builder(conservation_law=np.identity(np.arange(4)), ...).
Hope this helps, Anton

I know this is a very old discussion, but I'm in a similar position and want to look at a superconducting system with spin.
Have you been able to resolve this?
Best Regards, Daniel
