Anisotropy and suppression of spin--orbit interaction in a GaAs double quantum dot
Andrea Hofmann, Ville F. Maisi, Tobias Krähenmann +4
The spin-flip tunneling rates are measured in GaAs-based double quantum dots by time-resolved charge detection. Such processes occur in the Pauli spin blockade regime with two elec…
Measuring the degeneracy of discrete energy levels using a GaAs/AlGaAs quantum dot
Andrea Hofmann, Ville F. Maisi, Carolin Gold +8
We demonstrate an experimental method for measuring quantum state degeneracies in bound state energy spectra. The technique is based on the general principle of detailed balance, a…
Investigating Energy Scales of Fractional Quantum Hall States using Scanning Gate Microscopy
Beat A. Braem, Tobias Krähenmann, Szymon Hennel +4
We use the voltage biased tip of a scanning force microscope at a temperature of 35\,mK to locally induce the fractional quantum Hall state of in a split-gate defined const…
