Global $S O (3) \times S O (3) \times U (1)$ symmetry of the Hubbard model on bipartite lattices

J. M. P. Carmelo, Stellan Ostlund, M. J. Sampaio

It is found that for on-site interaction $U \neq = 0$ the local $S U (2) \times S U (2) \times U (1)$ gauge symmetry of the Hubbard model on a bipartite lattice with vanishing transfer inte…
