First Principles Based Simulations of Relaxor Ferroelectrics

Author(s)
Benjamin P. Burton, Eric J. Cockayne, Silvia Tinte, U Waghmare
The phenomenology of Pb(B,B$ {\prime}$)O$_{3}$, perovskite based relaxor ferroelectrics is reviewed, with emphasis on the relationship between chemical short...

Quantum key distribution at telecom wavelengths with noise-free detectors

Author(s)
Danna Rosenberg, Sae Woo Nam, Philip A. Hiskett, Charles G. Peterson, Richard J. Hughes, Jane E. Nordholt, Adriana Lita, Aaron J. Miller
The length of a secure link over which a quantum key can be distributed depends on the efficiency and dark-count rate of the detectors used at the receiver. We...

Nucleobase Orientation and Ordering in Films of Single-Stranded DNA on Gold

Author(s)
D Y. Petrovykh, V Perez-Dieste, A Opdahl, H Y. Kimura-Suda, J M. Sullivan, Michael J. Tarlov, F J. Himpsel, L J. Whitman
The structure of single-stranded DNA (ssDNA) immobilized on surfaces is critical to applications exploiting the molecular recognition function of nucleic acids...

Microwave SQUID multiplexers for low-temperature detectors

Author(s)
Kent D. Irwin, James A. Beall, W.Bertrand (Randy) Doriese, William Duncan, Gene C. Hilton, John Mates, Carl D. Reintsema, Dan Schmidt, Joel Ullom, Leila R. Vale, Barry L. Zink, Konrad Lehnert
We report on the development of a SQUID multiplexer operated at microwave frequencies. This multiplexer can accommodate any detector that can be read out with...

Molecular Beam Epitaxial Growth of High-Quality GaN Nanocolumns

Author(s)
J E. Van Nostrand, J. E. Averett, R Cortez, J. Boeckl, C Stutz, Norman Sanford, Albert Davydov, M M. Maska
Vertically oriented gallium nitride GaN nanocolumns (NCs) approximately 90±10 nm wide and 0.75 microns tall were grown by plasma-assisted molecular beam epitaxy...

Fabrication of Prototype Imaging Arrays for SCUBA-2

Author(s)
Gene C. Hilton, James A. Beall, W.Bertrand (Randy) Doriese, William Duncan, S. L. Ferreira, Kent D. Irwin, Carl D. Reintsema, Joel Ullom, Leila R. Vale, Yizi Xu, Barry L. Zink, William Parkes, Andrew S. Bunting, Camilla Dunare, Alan Gundlach, T. Stevenson, Anthony Walton, Eric Schulte, Elizabeth Corrales, Joseph P. Sienicki, Dan Bintley, Peter Ade, Rashmi Sudiwala, Adam L. Woodcraft, Mark Halpern, Wayne Holland, Damian Audley, Michael MacIntosh
Prototype imaging sub-arrays for SCUBA-2 (the Sub-millimeter Common-User Bolometer Array) have been fabricated and tested. The pixel count (1280) of these wafer...

Cryptographic Primitives Can Be Fragile

Author(s)
Rene C. Peralta
We show that a well-known coin-flipping protocol is breakable in the sense that one of the parties can pre-determine the result of the coin-flip. The way in...

Microwave Spectrum and Structure of Methyl Phosphonic Difluoride

Author(s)
R D. Suenram, Francis J. Lovas, David F. Plusquellic, M W. Elizy, J M. Lochner, J O. Jensen, A C. Samuels
The rotational spectrum of methyl phosphonic difluoride has been reinvestigated using a pulsed-molecular-beam Fabry-Perot cavity microwave spectrometer. The...
