Electrical read-out of the local nuclear polarization in the quantum Hall effect
A. Würtz, T. Müller, A. Lorke +2
It is demonstrated that the now well-established `flip-flop' mechanism of spin exchange between electrons and nuclei in the quantum Hall effect can be reversed. We use a sample geo…

Experimental investigation of early-time diffusion in the quantum kicked rotor using a Bose-Einstein condensate
G. Duffy, S. Parkins, T. Muller +3
We report the experimental observation of resonances in the early-time momentum diffusion rates for the atom-optical delta-kicked rotor. In this work a Bose-Einstein condensate pro…
