Is there spin-charge separation in the 2D Hubbard and t-J models at low electronic densities?

Y. C. Chen, A. Moreo, F. Ortolani +2

The spin and density correlation functions of the two-dimensional Hubbard model at low electronic density are calculated in the ground state by using the power method, and at…
