Spin orbit coupling at the level of a single electron
V. F. Maisi, A. Hofmann, M. Röösli +5
We utilize electron counting techniques to distinguish a spin conserving fast tunneling process and a slower process involving spin flips in AlGaAs/GaAs-based double quantum dots.…
Mode specific backscattering in a quantum point contact
A. A. Kozikov, R. Steinacher, C. Rössler +4
We demonstrate a scanning gate grid measurement technique consisting in measuring the conductance of a quantum point contact (QPC) as a function of gate voltage at each tip positio…
Non-local polarization feedback in a fractional quantum Hall ferromagnet
Szymon Hennel, Beat A. Braem, Stephan Baer +11
In a quantum Hall ferromagnet, the spin polarization of the two-dimensional electron system can be dynamically transferred to nuclear spins in its vicinity through the hyperfine in…
Mapping an electron wave function by a local electron scattering probe
Christian Reichl, Werner Dietsche, Thomas Tschirky +2
A technique is developed which allows for the detailed mapping of the electronic wave function in two-dimensional electron gases with low-temperature mobilities up to 15E6 cm^2/Vs.…
Single-Spin CCD
Timothy Alexander Baart, Mohammad Shafiei, Takafumi Fujita +3
Spin-based electronics or spintronics relies on the ability to store, transport and manipulate electron spin polarization with great precision. In its ultimate limit, information i…
Transition of a 2D spin mode to a helical state by lateral confinement
P. Altmann, M. Kohda, C. Reichl +2
Spin-orbit interaction (SOI) leads to spin precession about a momentum-dependent spin-orbit field. In a diffusive two-dimensional (2D) electron gas, the spin orientation at a given…
Magnetoplasma excitations of two-dimensional anisotropic heavy fermions in AlAs quantum wells
V. M. Muravev, A. R. Khisameeva, V. N. Belyanin +5
The spectra of plasma and magnetoplasma excitations in a two-dimensional system of anisotropic heavy fermions were investigated for the first time. The spectrum of microwave absorp…
Equilibrium free energy measurement of a confined electron driven out of equilibrium
Andrea Hofmann, Ville F. Maisi, Clemens Rössler +7
We study out-of equilibrium properties of a quantum dot in a GaAs/AlGaAs two-dimensional electron gas. By means of single electron counting experiments, we measure the distribution…
Microwave Emission from Hybridized States in a Semiconductor Charge Qubit
A. Stockklauser, V. F. Maisi, J. Basset +6
We explore the microwave radiation emitted from a biased double quantum dot due to the inelastic tunneling of single charges. Radiation is detected over a broad range of detuning c…
Capacitive coupling in hybrid Graphene-GaAs nanostructures
Pauline Simonet, Clemens Rössler, Tobias Krähenmann +5
Coupled hybrid nanostructures are demonstrated using the combination of lithographically patterned graphene on top of a two-dimensional electron gas (2DEG) buried in a GaAs/AlGaAs…
Transport Spectroscopy of a Spin-Coherent Dot-Cavity System
Clemens Rössler, David Oehri, Oded Zilberberg +8
Quantum engineering requires controllable artificial systems with quantum coherence exceeding the device size and operation time. This can be achieved with geometrically confined l…
