Optimized Dynamical Decoupling in a Model Quantum Memory

Author(s)
Michael J. Biercuk, Hermann Uys, Aaron Vandevender, N. Shiga, Wayne M. Itano, David J. Wineland, John J. Bollinger
We demonstrate the efficacy of optimized dynamical decoupling pulse sequences in suppressing phase errors in a model quantum memory. Our experimental system

Itinerant spin excitations near the hidden order transition in URu2Si2

Author(s)
J. A. Janik, H. D. Zhou, Y.-J. Jo, L. Balicas, G. J. MacDougall, G. M. Luke, J. D. Garrett, K. J. McClellan, E. D. Bauer, J. L. Sarrao, Yiming Qiu, John R. Copley, Z. Yamani, W. J. Buyers, C. R. Wiebe
By means of neutron scattering we show that the high-temperature precursor to the hidden order state of the heavy fermion superconductor URu 2Si 2 exhibits

A Ferroelectric Oxide Directly on Silicon

Author(s)
Joseph C. Woicik, Maitri P. Warusawithana, Cheng Cen, Charles R. Sleasman, Yulan Li, Jeffery Kluga, Lena F. Kourkoutis, Hao Li, Li-Peng Wang, Michael Bedzyk, David A. Muller, Long-Qing Chen, Jeremy Levy, Darrell G. Schlom
Silicon and silicon dioxide form what is arguably the most important technological interface. With the end of Moore s-law scaling for silicon fast approaching

Probing interactions between ultracold fermions

Author(s)
G K. Campbell, M M. Boyd, J W. Thomsen, M J. Martin, S Blatt, M D. Swallows, Travis L. Nicholson, Tara Fortier, Christopher W. Oates, Scott Diddams, Nathan D. Lemke, Pascal Naidon, Paul S. Julienne, Jun Ye, Andrew Ludlow
At ultracold temperatures, the Pauli exclusion principle suppresses collisions between identical fermions. This has motivated the development of atomic clocks

Viscosity of H20 in the Critical Region

Author(s)
Jan V. Sengers, Richard A. Perkins, Marcia L. Huber, Daniel G. Friend
It has been well established that thermodynamic and transport properties of fluids exhibit singular behavior near the critical point. In this paper we review

Demonstration of Impedance Matching Using a mu-Negative (MNG) Metamaterial

Author(s)
Christopher L. Holloway, R. B. Greegor, C. G. Parazzoli, J. A. Nielsen, M. H. Tanielian, D Vier, S Schultz, Richard Ziolkowski
A mu-negative (MNG) metamaterial hemisphere was used to demonstrate impedance matching for a magnetic loop. The metamaterial was comprised of copper spirals

A New Evaluation of the Half-life of 241Pu

Author(s)
Roger Wellum, Andre Verbruggen, Ruediger Kessel
A new evaluation of the half-life of 241Pu has been made by developing earlier methods and techniques and employing further measurements of the isotopic ratio

Measuring Pulse Energy With Solid-State Photodiodes

Author(s)
Robert E. Vest, Shannon B. Hill, Steven E. Grantham
With the advent of extreme ultraviolet lithography (EUVL) the measurement of the energy contained in pulses of short-wavelength radiation is becoming
