Oscillating magnetoresistance in graphene p-n junctions at intermediate magnetic fields
Hiske Overweg, Hannah Eggimann, Ming-Hao Liu +10
We report on the observation of magnetoresistance oscillations in graphene p-n junctions. The oscillations have been observed for six samples, consisting of single-layer and bilaye…
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…
Transport spectroscopy of singlet-triplet quantum dot states coupled to electronic cavities
Michael Sven Ferguson, Clemens Rössler, Thomas Ihn +3
A strong coupling between an electronic cavity and a quantum dot has been recently demonstrated [Phys. Rev. Lett. 115, 166603 (2015)] and described in a comprehensive theoretical f…
Heat dissipation and fluctuations in a driven quantum dot
Andrea Hofmann, Ville F. Maisi, Julien Basset +5
While thermodynamics is a useful tool to describe the driving of large systems close to equilibrium, fluctuations dominate the distribution of heat and work in small systems and fa…
Electron backscattering in a cavity: ballistic and coherent effects
A. A. Kozikov, D. Weinmann, C. Rossler +4
Numerous experimental and theoretical studies have focused on low-dimensional systems locally perturbed by the biased tip of a scanning force microscope. In all cases either open o…
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…
