NORMAL-STATE EFFECTIVE ACTION FOR THE FLUX-BINDING PHASE OF THE T-J MODEL

The normal-state transport properties are studied for the flux-binding phase of the t-J model, within the framework of gauge theory. We find that the resistivity is linearly temperature dependent with a relaxat ion rate HBAR/tau congruent-to 2k(B)T. We also show that the Hall coef ficient involves a second relaxation rate and the cotangent Hall angle follows a T2 law. Furthermore, the thermopower exhibits a strong dopi ng dependence. All these features are in good agreement with the trans port measurements of the high-T(c) copper oxide compounds.
