Current bistability and hysteresis in strongly correlated quantum wires
R. Egger, H. Grabert, A. Koutouza +2
Nonequilibrium transport properties are determined exactly for an adiabatically connected single channel quantum wire containing one impurity. Employing the Luttinger liquid model…
Is the direct observation of electronic coherence in electron transfer reactions possible?
A. Lucke, C. H. Mak, R. Egger +3
The observability of electronic coherence in electron transfer reactions is discussed. We show that under appropriate circumstances large-amplitude oscillations can be found in the…
Coulomb charging energy for arbitrary tunneling strength
Xiaohui Wang, Reinhold Egger, Hermann Grabert
The Coulomb energy of a small metallic island coupled to an electrode by a tunnel junction is investigated. We employ Monte Carlo simulations to determine the effective charging en…
High temperature anomaly of the conductance of a tunnel junction
Georg Goeppert, Xiaohui Wang, Hermann Grabert
The linear conductance of a tunnel junction in series with an ohmic resistor is determined in the high temperature limit. The tunneling current is treated nonperturbatively by mean…
Voltage-biased quantum wire with impurities
Reinhold Egger, Hermann Grabert
The bosonization technique to describe correlated electrons in a one-dimensional quantum wire containing impurities is extended to include an applied voltage source. The external r…
Friedel oscillations in Luttinger liquids
Reinhold Egger, Hermann Grabert
We study the density disturbance of a correlated 1D electron liquid in the presence of a scatterer or a barrier. The 2k_F-periodic density profile away from the barrier (Friedel os…
Coulomb Charging at Large Conduction
Xiaohui Wang, Hermann Grabert
We discuss the suppression of Coulomb charging effects on a small metallic island coupled to an electrode by a tunnel junction. At high temperatures the quantum corrections to the…
