Ultrafast optical rotations of electron spins in quantum dots
A. Greilich, Sophia E. Economou, S. Spatzek +5
Coherent manipulation of quantum bits (qubits) on time scales much shorter than the coherence time is a key prerequisite for quantum information processing. Electron spins in quant…
Observation of orientation- and -dependent Zeeman spin-splitting in hole quantum wires on (100)-oriented AlGaAs/GaAs heterostructures
J. C. H. Chen, O. Klochan, A. P. Micolich +6
We study the Zeeman spin-splitting in hole quantum wires oriented along the and crystallographic axes of a high mobility undoped (100)-oriented AlGaAs/GaAs he…
Spin noise of electrons and holes in self-assembled quantum dots
S. A. Crooker, J. Brandt, C. Sandfort +5
We measure the frequency spectra of random spin fluctuations, or "spin noise", in ensembles of (In,Ga)As/GaAs quantum dots (QDs) at low temperatures. We employ a spin noise spectro…
Quantized magnetic confinement in quantum wires
A. Tarasov, S. Hugger, Hengyi Xu +6
Ballistic quantum wires are exposed to longitudinal profiles of perpendicular magnetic fields composed of a spike (magnetic barrier) and a homogeneous part. An asymmetric magnetoco…
Hyperfine interaction mediated exciton spin relaxation in (In,Ga)As quantum dots
H. Kurtze, D. R. Yakovlev, D. Reuter +2
The population dynamics of dark and bright excitons in (In,Ga)As/GaAs quantum dots is studied by two-color pump-probe spectroscopy in an external magnetic field. With the field app…
