Molecular electronics in junctions with energy disorder
Franz J. Kaiser, Peter Hänggi, Sigmund Kohler
We investigate transport through molecular wires whose energy levels are affected by environmental fluctuations. We assume that the relevant fluctuations are so slow that they, wit…
Theoretical and experimental investigations of Coulomb blockade in coupled quantum dot systems
F. J. Kaiser, S. Kohler, P. Hänggi +7
Two strongly coupled quantum dots are theoretically and experimentally investigated. In the conductance measurements of a GaAs based low-dimensional system additional features to t…
Landau-Zener transitions in qubits controlled by electromagnetic fields
Martijn Wubs, Keiji Saito, Sigmund Kohler +2
We investigate the influence of a dipole interaction with a classical radiation field on a qubit during a continuous change of a control parameter. In particular, we explore the no…
Nonadiabatic Electron Pumping: Maximal Current with Minimal Noise
Michael Strass, Peter Hänggi, Sigmund Kohler
The noise properties of pump currents through an open double quantum dot setup with non-adiabatic ac driving are investigated. Driving frequencies close to the internal resonances…
Coherence stabilization of a two-qubit gate by AC fields
Karen M. Fonseca Romero, Sigmund Kohler, Peter Hänggi
We consider a CNOT gate operation under the influence of quantum bit-flip noise and demonstrate that ac fields can change bit-flip noise into phase noise and thereby improve cohere…
Vibrational effects in laser driven molecular wires
Jörg Lehmann, Sigmund Kohler, Volkhard May +1
The influence of an electron-vibrational coupling on the laser control of electron transport through a molecular wire that is attached to several electronic leads is investigated.…
