Quantum Feedback in nuclear spin-assisted electronic transport — •Klemens Mosshamer and Tobias Brandes — Institut für theoretische Physik, Technische Universität Berlin, Hardenbergstrasse 36, 10623 Berlin

We investigate theoretically the electronic transport through quantum dot systems that interact with the nuclear environment via the hyperfine interaction. We show that the non-linear dynamics arising due to the hyperfine interaction can be controlled via closed-loop feedback operations, such as time-dependent modifications of the tunneling rate.
