Here I present code to develop the solutions for treatments of the Hubbard model, inluding:
- t=0, single-site approximation
- exact diagonalization for a 1x2 lattice
- exact diagonalization for a 2x2 lattice
Both of the exact diagonalization codes assume half-filling and an equal number of spin up and spin down particles. The 2x2 code can be generalized for 3D lattices of arbitrary sites lxmxn, however not a lot of testing has been performed for systems above 1x2x2.
