Spin-Incoherent Transport in Quantum Wires
W. K. Hew, K. J. Thomas, M. Pepper +4
When a quantum wire is weakly confined, a conductance plateau appears at e^2/h with decreasing carrier density in zero magnetic field accompanied by a gradual suppression of the 2e…
Charge pumping in carbon nanotube quantum dots
M. R. Buitelaar, V. Kashcheyevs, P. J. Leek +6
We investigate charge pumping in carbon nanotube quantum dots driven by the electric field of a surface acoustic wave. We find that at small driving amplitudes, the pumped current…
Field-tunable magnetic phases in a semiconductor-based two-dimensional Kondo lattice
C. Siegert, A. Ghosh, M. Pepper +4
We show the existence of intrinsic localized spins in mesoscopic high-mobility GaAs/AlGaAs heterostructures. Non-equilibrium transport spectroscopy reveals a quasi-regular distribu…
Sensitivity of the magnetic state of a spin lattice on itinerant electron orbital phase
C. Siegert, A. Ghosh, M. Pepper +4
Spatially extended localized spins can interact via indirect exchange interaction through Friedel oscillations in the Fermi sea. In arrays of localized spins such interaction can l…
