Integrability-based analysis of the hyperfine-interaction -nduced decoherence in quantum dots
Alexandre Faribault, Dirk Schuricht
Using the Algebraic Bethe Ansatz in conjunction with a simple Monte Carlo sampling technique, we study the problem of the decoherence of a central spin coupled to a nuclear spin ba…
On the nature of tunable hole g-factors in quantum dots
N. Ares, V. N. Golovach, G. Katsaros +5
Electrically tunable g-factors in quantum dots are highly desirable for applications in quantum computing and spintronics. We report giant modulation of the hole g-factor in a SiGe…
Time-Resolved Magnetic Relaxation of a Nanomagnet on Subnanosecond Time Scales
H. Liu, D. Bedau, J. Z. Sun +4
We present a two-current-pulse temporal correlation experiment to study the intrinsic subnanosecond nonequilibrium magnetic dynamics of a nanomagnet during and following a pulse ex…
Tunneling in double barrier junctions with 'hot spots'
D. Herranz, F. G. Aliev, C. Tiusan +3
We investigate electronic transport in epitaxial Fe(100)/MgO/Fe/MgO/Fe double magnetic tunnel junctions with soft barrier breakdown (hot spots). Specificity of these junctions are…
Artificial Kagome Arrays of Nanomagnets: A Frozen Dipolar Spin Ice
N. Rougemaille, F. Montaigne, B. Canals +8
Magnetic frustration effects in artificial kagome arrays of nanomagnets are investigated using x-ray photoemission electron microscopy and Monte Carlo simulations. Spin configurati…
Spin-transfer pulse switching: From the dynamic to the thermally activated regime
D. Bedau, H. Liu, J. Z. Sun +4
The effect of thermal fluctuations on spin-transfer switching has been studied for a broad range of time scales (sub-ns to seconds) in a model system, a uniaxial thin film nanomagn…
