You refer to "atoms" and "unit cell", so I presume that you are trying to create a system with translational symmetry, and that each Kwant *site* corresponds to a single atom. It is not 100% clear to me what you want when you say "the eigenvectors and eigenvalue" of your Hamiltonian; if your system has translational symmetry then presumably you want the eigen-decomposition *at a given quasi-momentum*, but you do not explicitly state this, so I am not sure. Posting a complete code example is useful because it is more precise than describing your problem with words. Happy Kwanting, Joe
