Current-Voltage Asymmetries in Two Level Systems

Part of the Lecture Notes in Physics book series (LNP, volume 809)

Abstract

We consider current-voltage asymmetries in double quantum dot systems. Such effects are here described in terms of correlation effects and we use the one-loop-approximation to find that asymmetric couplings to the left and right leads which provide asymmetric response to the bias voltage. We discuss the results in terms of the relative level spacing, detuning, and the hopping rate between the quantum dots.
