Abstract
⺠Accurate ground state energies of 4 Ã 4 two-dimensional Hubbard model were obtained. ⺠By using the second-order reduced density matrix. ⺠Employing N-representability as P, Q, G, T1 and T2â². ⺠Highly correlated region of parameter 4 < U/t < 10. ⺠The energy deviations per site were only â¼0.01.
