COM(3p) solution of the 2D Hubbard model: momentum resolved quantities
Adolfo Avella
Recently, within the framework of the Composite Operator Method, it has been proposed a three-pole solution for the two-dimensional Hubbard model [Eur. Phys. J. B 87, 45 (2014)], w…
Composite Operator Method analysis of the underdoped cuprates puzzle
Adolfo Avella
The microscopical analysis of the unconventional and puzzling physics of the underdoped cuprates, as carried out lately by means of the Composite Operator Method (COM) applied to t…
Polaron in the t-J Models with Three-Site Terms: the SU(2) and the Ising Cases
Krzysztof Wohlfeld
We compare the role of the three-site terms added to the t-J models in the SU(2) and the Ising cases in the extremely low doping regime, i.e. when a single hole added to the strong…
The energy-scale-dependent Composite Operator Method for the single-impurity Anderson model
Adolfo Avella, Ferdinando Mancini, Roland Hayn
The recently developed energy-scale-dependent Composite Operator Method is applied to the single-impurity Anderson model. A fully self-consistent solution is given and analyzed. At…
