Forcing inertial Brownian motors: efficiency and negative differential mobility
Marcin Kostur, Lukasz Machura, Peter Hänggi +2
The noise-assisted, directed transport in a one-dimensional dissipative, inertial Brownian motor of the rocking type that is exposed to an external bias is investigated. We demonst…
Improving the purity of one- and two-qubit gates by AC fields
Sigmund Kohler, Peter Hänggi
We investigate the influence of AC driving fields on the coherence properties of one- and two-qubit gate operations. In both cases, we find that for suitable driving parameters, th…
Universal Approach to Overcoming Nonstationarity, Unsteadiness and Non-Markovity of Stochastic Processes in Complex Systems
Renat M. Yulmetyev, Anatolii V. Mokshin, Peter Hänggi
In present paper we suggest a new universal approach to study complex systems by microscopic, mesoscopic and macroscopic methods. We discuss new possibilities of extracting informa…
Coherent charge transport through molecular wires: influence of strong Coulomb repulsion
Franz J. Kaiser, Michael Strass, Sigmund Kohler +1
We derive a master equation for the electron transport through molecular wires in the limit of strong Coulomb repulsion. This approach is applied to two typical situations: First,…
100 Years of Brownian motion
Peter Hänggi, Fabio Marchesoni
In the year 1905 Albert Einstein published four papers that raised him to a giant in the history of science of all times. These works encompass the photon hypothesis (for which he…
