Electron tunneling into a quantum wire in the Fabry-Perot regime
Stefano Pugnetti, Fabrizio Dolcini, Dario Bercioux +1
We study a gated quantum wire contacted to source and drain electrodes in the Fabry-Perot regime. The wire is also coupled to a third terminal (tip), and we allow for an asymmetry…
Negativity of the excess noise in a quantum wire capacitively coupled to a gate
F. Dolcini, B. Trauzettel, I. Safi +1
The electrical current noise of a quantum wire is expected to increase with increasing applied voltage. We show that this intuition can be wrong. Specifically, we consider a single…
Charge and spin dynamics of interacting Fermions in a one dimensional harmonic trap
Lars Kecke, Hermann Grabert, Wolfgang Häusler
We study an atomic Fermi gas interacting through repulsive contact forces in a one dimensional harmonic trap. Bethe-Ansatz solutions lead to an inhomogeneous Tomonaga-Luttinger mod…
Transport properties of single channel quantum wires with an impurity: Influence of finite length and temperature on average current and noise
Fabrizio Dolcini, Bjoern Trauzettel, Ines Safi +1
The inhomogeneous Tomonaga Luttinger liquid model describing an interacting quantum wire adiabatically coupled to non-interacting leads is analyzed in the presence of a weak impuri…
Appearance of fractional charge in the noise of non-chiral Luttinger liquids
B. Trauzettel, I. Safi, F. Dolcini +1
The current noise of a voltage biased interacting quantum wire adiabatically connected to metallic leads is computed in presence of an impurity in the wire. We find that in the wea…
Oscillatory non-linear conductance of an interacting quantum wire with an impurity
Fabrizio Dolcini, Hermann Grabert, Ines Safi +1
The nonlinear conductance of a one-dimensional quantum wire adiabatically coupled to Fermi Liquid electron reservoirs is determined in presence of an impurity. We show that electro…
