A Study of the Antiferromagnetic Phase in the Hubbard Model by means of the Composite Operator Method
Adolfo Avella, Ferdinando Mancini, Roland Muenzner
We have investigated the antiferromagnetic phase of the 2D, the 3D and the extended Hubbard models on a bipartite cubic lattice by means of the Composite Operator Method within a t…
