Here is what I wish to know. Specifying a tight binding hamiltonian requires values of potential (U). Consider a 3d solid. If I have potential profile in x direction (U1, U2, U3...so on) can I directly plug in these U values into the tight binding hamiltonian or do I need to do some transformation (like change of space etc) before I can plug in 'potential values vs X' into Hamiltonian.
