Abstract

We present exact results for the T = 0 ground state of the t-J model in one dimension in the low-concentration limit and arbitrary coupling constants. The procedure is based on the construction of the ground-state wavefunction in real space by the enumeration of the possible local particle configurations and taking into account the translational and rotational invariance of the system. Concrete results are presented for two- and four-particle cases.
