Abstract
The question of spin-charge separation in two-dimensional lattices has been addressed by numerical simulations of the motion of one hole in a half-filled band. The calculations have been performed on finite clu sters with Hubbard and t-J models. By comparing the time evolution of spin and charge polarization currents in one and two dimensions, evide nce in favor of spin-charge separation in two dimensions is presented. In contrast with this, spin-charge separation is absent in a highly d oped, metallic, system.
