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…

Charge redistribution between cyclotron-resolved edge states at high imbalance
E. V. Deviatov, V. T. Dolgopolov, A Wurtz
We use a quasi-Corbino sample geometry with independent contacts to different edge states in the quantum Hall effect regime to investigate a charge redistribution between cyclotron…

Manifestation of the bulk phase transition in the edge energy spectrum in a two dimensional bilayer electron system
E. V. Deviatov, A. Wurtz, A. Lorke +5
We use a quasi-Corbino sample geometry with independent contacts to different edge states in the quantum Hall effect regime to investigate the edge energy spectrum of a bilayer ele…
