抄録
A new anisotropic t-J model in one dimension is proposed which has long-range hopping and exchange. This t-J model is only partially solvable in contrast to known integrable models with long-range interaction. In the high-density limit the model reduces to the XXZ chain with the long-range exchange.Some exact eigenfunctions are shown to be of the Jastrow type if certain conditions for an anisotropy parameter are satisfied. The ground state as well as the excitation spectrum for various values of the anisotropy parameter and filling are derived numerically.It is found that the Jastrow-type wave function is an excellent trial function for any value of the anisotropy parameter.
