Renormalization-Group Approach to a Three-Legs Fermionic Ladder
Enrico Arrigoni
We study the spin and charge phase diagram of a three-legs ladder (at zero temperature) as a function of fermion density and of transverse single-particle hopping by means of a Ren…

On an exact criterion for choosing the hopping operator in the four-slave-boson approach
E. Arrigoni, G. C. Strinati
We consider the -component generalization of the four-slave-boson approach to the Hubbard model, where acts as the small parameter that controls the fluctuations about the…

On the correct continuum limit of the functional-integral representation for the four-slave-boson approach to the Hubbard model: Paramagnetic phase
E. Arrigoni, G. C. Strinati
The Hubbard model with finite on-site repulsion U is studied via the functional-integral formulation of the four-slave-boson approach by Kotliar and Ruckenstein. It is shown that a…
