Charge Conjugation and Pairing in a model CuO Cluster
Michele Cini, Adalberto Balzarotti, Gianluca Stefanucci
Highly-symmetric three-band Hubbard Cu-O clusters have peculiar properties when the hole number is such that they admit W=0 hole pairs. These are two-hole eigenstates of the on-sit…

Pairing in the Three-Band Hubbard Model of the Cu-O Plane
Michele Cini, Gianluca Stefanucci, Adalberto Balzarotti
By a canonical transformation of the three-band Hubbard model, we introduce an effective Hamiltonian for the propagation of two holes doped into the ground state of the Cu-O plane.…
