Abstract

We study the one-dimensional deformed t -t′ - J model in terms of the continuum field theories. We found that at low doping concentration and far away from the phase separation regime, there are two phases: the Luttinger liquid and the Luther-Emery liquid, depending on t′/t < (t′/t)c or t′/t > (t′/t)c, where (t′/t)c > 0. Moreover, the singlet superconducting correlations are dominant in the Luther-Emery liquid.
