摘要：

Via a large-N slave-boson formulation of the t-J model on the square lattice, we study the stability of generalized flux phases as a function of electronic filling fraction in the mean-field approximation. At zero temperature we find that there exists a critical hopping parameter, below which a phase with flux quanta per plaquette given by the filling fraction is stable, and above which a fluxless uniform phase is stable. © 1990 The Japan Society of Applied Physics.
