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…
The metal-insulator transition in one dimension
H. J. Schulz
The low--energy excited states of a system of interacting one--dimensional fermions in a conducting state are collective charge and spin density oscillations. The unusual physical…
Functional Integrals for Correlated Electrons
H. J. Schulz
The application of functional integral methods and the Hubbard--Stratonovich transformation to the Hubbard model is discussed. For the attractive case, using a simple gauge transfo…
Interacting fermions in one dimension: from weak to strong correlation
H. J. Schulz
Lecture notes from the Jerusalem Winter School on Theoretical Physics "Correlated Electron Systems", Dec. 1991 -- Jan. 1992. Contains a review of recent and not so recent results i…
