Weakly correlated electrons on a square lattice: a renormalization group theory
D. Zanchi, H. J. Schulz
We formulate the exact Wilsonian renormalization group for a system of interacting fermions on a lattice. The flow equations for all vertices of the Wilson effective action are exp…
SO(N) symmetries in the two--chain model of correlated fermions
H. J. Schulz
The two-chain model of correlated fermions, appropriate e.g. for doped spin ladders or carbon nanotubes, is investigated in the weak-interaction limit. It is shown that the model s…
Fermi liquids and Luttinger liquids
H. J. Schulz, G. Cuniberti, P. Pieri
In these lecture notes, the basic physics of Fermi liquids and Luttinger liquids is presented. Fermi liquids are discussed both from a phenomenological viewpoint, in relation to mi…
On the metal-insulator transition in the two-chain model of correlated fermions
H. J. Schulz
The doping-induced metal-insulator transition in two-chain systems of correlated fermions is studied using a solvable limit of the t-J model and the fact that various strong- and w…
Interacting electrons with spin in a one-dimensional wire connected to leads
Inès Safi, H. J. Schulz
We investigate a one--dimensional wire of interacting electrons connected to one--dimensional noninteracting leads in the absence and in the presence of a backscattering potential.…
Transport in a one-dimensional wire connected to leads and proximity effects
I. Safi, H. J. Schulz
We investigate transport through a finite interacting wire connected to noninteracting leads. The conductance of the pure wire is not renormalized by the interactions for any spati…
