The Mott-Hubbard transition and the paramagnetic insulating state in the two-dimensional Hubbard model

F. Mancini

The Mott-Hubbard transition is studied in the context of the two-dimensional Hubbard model. Analytical calculations show the existence of a critical value Uc of the potential stren…

Comment on "Symmetry properties of magnetization in the Hubbard model at finite temperature"

A. Avella, F. Mancini, D. Villani

The results of G. Su and M. Suzuki [Phys. Rev. B 54, 8291 (1996); ibidem 57, 13367 (1998)] for the spin and pseudo-spin symmetry properties of the Hubbard model are reexamined. We…

The N-Chain Hubbard model in the Composite Operator Method

A. Avella, F. Mancini, M. M. Sanchez +1

We propose a theoretical framework to describe the ladder systems. The N-chain Hubbard model has been studied within the Composite Operator Method. In this scheme of calculations t…

The overdoped regime in LSCO

A. Avella, F. Mancini, D. Villani

Recent experimental data for the overdoped LSCO have firmly established the properties which characterize the transition between the superconducting and the Fermi liquid metallic p…
