Danani, Andrea and Pelizzola, Alessandro (1992) Cluster Variation Approach to the Antiferromagnetic Transition of the t-J Model. Modern Physics Letters B, 7 (27). p. 1583. ISSN 0217-9849
Full text not available from this repository.Abstract
The antiferromagnetic phase transition associated with the breaking of the magnetic SU(2) symmetry of the t-J model is investigated by means of the cluster variation method in the pair approximation. The disordered and antiferromagnetic phases are characterized by means of their symmetry properties, and an analytical implicit expression is given for the Néel temperature.
