I'd like to know if it is possible to construct/attach leads with lattices different from the main scattering region, or even leads with custom geometry unrelated to the scattering region?
For example if my scattering region is an amorphous cluster whose geometry have defined by hand, and I want to build leads using their own lattice to the left and right. Is that allowed in KWANT?
(Of course in that case one would need define bonds/hoppings between and within the leads, and also from the lead to the main scattering region... but how..)
