Title: Quantum Phase Diagram of the t-J{sub z} Chain Model

Journal Article · · Physical Review Letters

We present the quantum phase diagram of the one-dimensional t -J{sub z} model for arbitrary spin (integer or half-integer) and sign of the spin-spin interaction J{sub z} , using an exact mapping to a spinless fermion model that can be solved exactly using the Bethe ansatz. We discuss its superconducting phase as a function of hole doping {nu} . Motivated by the new paradigm of high temperature superconductivity, the stripe phase, we also consider the effect the antiferromagnetic background has on the t -J{sub z} chain intended to mimic the stripe segments.
