Description

The four site Hubbard model is considered from the exact diagonalization and variational method points of view. We show that a symmetry projected mean-field theory recovers the exact ground state energy, irrespective of the interaction strength, in contrast to the conventional Gutzwiller wave-function that will be also considered.
