Auger spectroscopy of strongly correlated systems: present status and future trends
Claudio Verdozzi, Michele Cini, Andrea Marini
We review the Cini-Sawatzky approach to the line shape analysis of Auger CVV transitions, in its basic and original formulation. Then, several extensions of the theory are reviewed…
Pairing Mechanism in the doped Hubbard Antiferromagnet: the Model as a Test Case
Michele Cini, Enrico Perfetto, Gianluca Stefanucci
We introduce a {\em local} formalism, in terms of eigenstates of number operators, having well defined point symmetry, to solve the Hubbard model at weak coupling on a …
Antiferromagnetism of the 2D Hubbard Model at Half Filling: Analytic Ground State at Weak Coupling
Michele Cini, Gianluca Stefanucci
We introduce a local formalism to deal with the Hubbard model on a N times N square lattice (for even N) in terms of eigenstates of number operators, having well defined point symm…
Exact Ground State of the 2D Hubbard Model at Half Filling for
Michele Cini, Gianluca Stefanucci
We solve analytically the square lattice Hubbard model for even at half filling and weak coupling by a new approach. The exact ground state wave function provides a…
Canonical Transformation of the Hubbard Model and W=0 Pairing: Comparison with Exact Diagonalization Results
Michele Cini, Adalberto Balzarotti, Raffaella Brunetti +2
We have recently developed a canonical transformation of the Hubbard and related models, valid for systems of arbitrary size and for the full plane; this is particularly suited to…
