Hi I've been reading about the tight-binding model, and I have some questions. Lets say we have the Hamiltonian H for our lattice, and it satisfies Hψ = Eψ, where ψ is a vector containing the wavefunction for each atom in the lattice. When I solve the above equation e.g. numerically, I get the eigenvectors ψ. In my case the ψ's just contain numbers, but does this mean that the waverfuncion for each atom is constant?
