Dear Kwant users, I have two questions: 1) Specifying conservation laws is necessary only when transport calculations are done? If I am trying to compute ldos and bands should I bother with properly defining the conservation laws? 2) I was trying to implement a system with leads along the x-direction. However, along the y-direction, half of it is superconducting and the other half is not. How can I define the conservation law in such case since it is not possible to use a conservation law for all y values in the lead?
