Diffuse Interstellar Bands in z < 0.6 CaII Absorbers
Sara L. Ellison, Brian A. York, Michael T. Murphy +3
The diffuse interstellar bands (DIBs) probably arise from complex organic molecules whose strength in local galaxies correlates with neutral hydrogen column density, N(HI), and dus…
Quantum key distribution using a triggered quantum dot source emitting near 1.3 microns
P. M. Intallura, M. B. Ward, O. Z. Karimov +5
We report the distribution of a cryptographic key, secure from photon number splitting attacks, over 35 km of optical fiber using single photons from an InAs quantum dot emitting ~…
High redshift FRII radio sources: large-scale X-ray environment
Elena Belsole, Diana M. Worrall, Martin J. Hardcastle +1
We investigate the properties of the environment around 20 powerful radio galaxies and quasars at redshifts between 0.45 and 1. Using XMM-Newton and Chandra observations we probe t…
Probing e-e interactions in a periodic array of GaAs quantum wires
Y. Jompol, C. J. B. Ford, I. Farrer +5
We present the results of non-linear tunnelling spectroscopy between an array of independent quantum wires and an adjacent two-dimensional electron gas (2DEG) in a double-quantum-w…
Comment on "Limits on the Time Variation of the Electromagnetic Fine-Structure Constant in the Low Energy Limit from Absorption Lines in the Spectra of Distant Quasars"
Michael T. Murphy, John K. Webb, Victor V. Flambaum
In their Letter [Phys. Rev. Lett. 92, 121302 (2004)] (also [Astron. Astrophys. 417, 853 (2004)]), Srianand et al. analysed optical spectra of heavy-element species in 23 absorption…
Phase diagram and magnetocaloric effect of CoMnGe_{1-x}Sn_{x} alloys
J. B. A. Hamer, R. Daou, S. Özcan +3
We propose the phase diagram of a new pseudo-ternary compound, CoMnGe_{1-x}Sn_{x}, in the range x less than or equal to 0.1. Our phase diagram is a result of magnetic and calometri…
