Hey mate!
I'm not enough of an expert that I could, say, write a TB code, but here's what I get. In order to describe a wavefunction you need to write it down as a linear combination of some set of 'basis' functions:
ψ=∑iciψiψ
In general, you can then write the Hamiltonian as a matrix whose elements correspond to the kinetic and potential energy terms for each of these basis functions.
Thanks for the question!
