Currents in a chain of quantum dots — •Klaus Morawetz — Münster University of Applied Sciences,Stegerwaldstrasse 39, 48565 Steinfurt, Germany — International Institute of Physics (IIP)Av.

Using the quantum kinetic equation analytical expressions for the currents in chains of quantum dots are derived. During the transient behaviour non-dissipative quantum correlations lead to a decay of the initial correlations. After this short time behaviour the total current for homogeneous electric fields is ballistic. For wavelength-modulated electric fields, an effective capacitance, inductance and Ohmic resistance can be realized given in terms of quantum parameter.
