Multipolar hierarchy of efficient quantum polarization measures
P. de la Hoz, A. B. Klimov. G. Bjork, Y. -H. Kim +4
We advocate a simple multipole expansion of the polarisation density matrix. The resulting multipoles appear as successive moments of the Stokes variables and can be obtained from…
Light transport in cold atoms: the fate of coherent backscattering in the weak localization regime
D. Wilkowski, Y. Bidel, T. Chaneliere +5
The recent observation of coherent backscattering (CBS) of light by atoms has emphasized the key role of the velocity spread and of the quantum internal structure of the atoms. Fir…
Spin dependent quantum transport effects in Cu nanowires
D. M. Gillingham, C. Muller, J. A. C. Bland
In this work we investigate quantum transport in Cu nanowires created by bringing macroscopic Cu wires into and out of contact under an applied magnetic field in air. Here we show…
In-situ Tuning of the Electric Dipole Strength of a Double Dot Charge Qubit: Charge Noise Protection and Ultra Strong Coupling
P. Scarlino, J. H. Ungerer, D. J. van Woerkom +10
Semiconductor quantum dots, where electrons or holes are isolated via electrostatic potentials generated by surface gates, are promising building blocks for semiconductor-based qua…
The Gamma-Ray Blazar PKS 0208-512, a Multi-Wavelength Investigation
J. M. Blanchard, J. E. J. Lovell, J. Dickey +8
The gamma-ray blazar PKS 0208-512 has shown strong periods of flaring, at all frequencies from radio to gamma-ray. This has led to its inclusion in the TANAMI project, which tracks…
