A Single Impurity in Tomonaga-Luttinger Liquids
Yuval Oreg, Alexander M. Finkel'stein
The problem of a single impurity in one dimensional Tomonaga-Luttinger liquids with a repulsive electron-electron interaction is discussed. We find that the renormalization group f…
Reply to the Comment on "Enhancement of the Tunneling Density of States in Tomonaga-Luttinger Liquids"
Yuval Oreg, Alexander M. Finkel'stein
In their comment Fabrizio and Gogolin dispute our result of the enhancement of the tunneling density of states in a Tomonaga-Luttinger liquid at the location of a backward scatteri…
DC--Transport in Quantum Wires
Yuval Oreg, Alexander M. Finkel'stein
The influence of electron--electron interaction on two terminal DC conductance of one--dimensional quantum wires is studied. A cancelation between the effect of the electron--elect…
Resonance in One--Dimensional Fermi--Edge Singularity
Yuval Oreg, Alexander M. Finkel'stein
The problem of the Fermi--edge singularity in a one--dimensional Tomonaga--Luttinger liquid is reconsidered. The backward scattering of the conduction band electrons on the impurit…
Enhancement of the tunneling density of states in Tomonaga--Luttinger Liquids
Yuval Oreg, Alexander M. Finkel'stein
We have calculated the tunneling density of states (DOS) at the location of a backward scattering defect for quantum wires and for edge state electrons in quantum Hall systems. A s…
Inter-Edge interaction in the Quantum Hall Effect
Yuval Oreg, Alexander M. Finkel'stein
We consider effects of the interaction between electrons drifting along the opposite sides of a narrow sample under the conditions of the quantum Hall effect. A spatial variation o…
