Exact study of charge-spin separation, pairing fluctuations, and pseudogaps in four-site Hubbard clusters

An exact study of charge-spin separation, pairing fluctuations, and pseudogaps is carried out by combining the analytical eigenvalues of the four-site Hubbard clusters with the grand canonical and canonical ensemble approaches in a multidimensional parameter space of temperature
