Local control of spin flow in weak magnetic fields
J. -H. Quast, G. V. Astakhov, W. Ossau +4
We demonstrate that optical illumination strongly influences spin transport in n-type GaAs. Specifically, increasing the power density of optical spin pumping results in a signific…

Experimental realization of highly-efficient broadband coupling of single quantum dots to a photonic crystal waveguide
T. Lund-Hansen, S. Stobbe, B. Julsgaard +5
We present time-resolved spontaneous emission measurements of single quantum dots embedded in photonic crystal waveguides. Quantum dots that couple to the photonic crystal waveguid…

Activated Behavior of the 0.7 2(e^2)/h Conductance Anomaly in Quantum Point Contacts
A. Kristensen, H. Bruus, A. Forchel +5
The 0.7 conductance anomaly in the quantized conductance of trench etched GaAs quantum point contacts is studied experimentally. The temperature dependence of the anomaly measured…
