Phase diagram of the one-dimensional tJ model — •Jochen Hub, Catia Lavalle, and Alejandro Muramatsu — Universität Stuttgart, Pfaffenwaldring 57, 70550 Stuttgart

Using a recently developed hybrid-loop algorithm [1] we determine the phase diagram of the tJ model in one-dimension, where a Luttinger-liquid phase (with Kρ<1 and Kρ>1), a spin-gap phase and a region of phase-separation are determined on the basis of a detailed finite-size scaling.
