Optical Detection of Single-Electron Spin Decoherence in a Quantum Dot
Oliver Gywat, Hans-Andreas Engel, Daniel Loss +3
We propose a method based on optically detected magnetic resonance (ODMR) to measure the decoherence time of a single electron spin in a semiconductor quantum dot. The elec…
Measuring the entanglement of coupled spins by multiphoton interference
Michael N. Leuenberger, Michael E. Flatte, D. D. Awschalom
We propose an experimental method to measure the entanglement of coupled spins, each in a separate quantum dot, by means of multiphoton interference patterns generated through the…
Local Manipulation of Nuclear Spin in a Semiconductor Quantum Well
M. Poggio, G. M. Steeves, R. C. Myers +3
The shaping of nuclear spin polarization profiles and the induction of nuclear resonances are demonstrated within a parabolic quantum well using an externally applied gate voltage.…
Voltage control of nuclear spin in ferromagnetic Schottky diodes
R. J. Epstein, J. Stephens, M. Hanson +4
We employ optical pump-probe spectroscopy to investigate the voltage dependence of spontaneous electron and nuclear spin polarizations in hybrid MnAs/n-GaAs and Fe/n-GaAs Schottky…
Damping of micromechanical structures by paramagnetic relaxation
J. G. E. Harris, R. Knobel, K. D. Maranowski +3
We find that the damping of micromechanical cantilevers is sensitive to the relaxation dynamics of paramagnetic ions contained within the levers. We measure cantilevers containing…
Independent Electronic and Magnetic Doping in (Ga,Mn)As Based Digital Ferromagnetic Heterostructures
E. Johnston-Halperin, J. A. Schuller, C. S. Gallinat +6
Ferromagnetic semiconductors promise the extension of metal-based spintronics into a material system that combines widely tunable electronic, optical, and magnetic properties. Here…
