The competition between nonmagnetic states and short-range antiferromagnetically-ordered RVB states in the t-J model is examined, and a finite temperature phase diagram is presented. For a wide range of temperatures and dopings, the stable phase results in a state in which both the flux and the RVB parameters are nonzero.

Abstract
The competition between nonmagnetic states and short-range antiferromagnetically-ordered RVB states in the t-J model is examined, and a finite temperature phase diagram is presented. For a wide range of temperatures and dopings, the stable phase results in a state in which both the flux and the RVB parameters are nonzero.File in questo prodotto:
