Volumetric Performance Evaluation of a Laser Scanner Based on Geometric Error Model

Author(s)
Balasubramanian Muralikrishnan, Massimiliano M. Ferrucci, Daniel S. Sawyer, Grant Gerner, Vincent D. Lee, Christopher J. Blackburn, Steven D. Phillips, Yuri Yakovlev, Andrey Astrelin, Spike Milligan, John Palmateer
We discuss a geometric error model for those large volume laser scanners that have the laser source and a spinning prism mirror mounted on a platform that can

Substitution of Ni for Fe in Superconducting Fe0.98Te0.5Se0.5 Depresses the Normal-State Conductivity but not the Magnetic Spectral Weight

Author(s)
Jinghui Wang, Ruidan Zhong, Shichao Li, Yuan Gan, Zhijun Xu, Cheng Zhang, T Ozaki, M. Matsuda, Yang Zhao, Qiang Li, Guangyong Xu, Genda Gu, J. M. Tranquada, R. J. Birgeneau, Jinsheng Wen
We have performed systematic resistivity and inelastic neutron scattering measurements on Fe 0.98-zNi zTe 0.5Se 0.5 samples to study the impact of Ni

Optical Lattice Clocks

Author(s)
Andrew D. Ludlow, Christopher W. Oates
Here we introduce and give a basic description of optical lattice clocks. We also briefly describe recent advances in these atomic frequency standards, looking

Atomic Clock with 1x10-18 Room-Temperature Blackbody Stark Uncertainty

Author(s)
Kyle P. Beloy, Nathan M. Hinkley, Nate B. Phillips, Jeffrey A. Sherman, Marco Schioppo, John H. Lehman, Ari D. Feldman, Leonard M. Hanssen, Christopher W. Oates, Andrew D. Ludlow
The Stark shift due to blackbody radiation (BBR) is a key factor limiting the performance of many atomic frequency standards, with the BBR environment inside

Tailor-Made Polyamide Membranes for Water Desalination

Author(s)
Edwin P. Chan, Wansuk Chol, Joona Bang, Jong Suk Lee, Jung-Hyun Lee, Joung-Eun Gu
Independent control over the extrinsic and intrinsic properties of the polyamide selective layer is critical when designing water desalination reverse osmosis

Fluctuating Defects in the Incipient Relaxor K1-xLixTaO3 (x=0.02)

Author(s)
C. Stock, Peter M. Gehring, G. Xu, Daniel Lamago, Dmitry Reznik, M. Russina, Jinsheng Wen, Lynn A. Boatner
We report neutron scattering measurements of the structural correlations associated with the apparent relaxor transition in K 1-xLi xTaO 2 for x=0.02 (KLT(0.02)

3D TEM Tomography of Templated Bilayer Films of Block Copolymers

Author(s)
Kevin W. Gotrik, Thomas F. Lam, Adam F. Hannon, Wubin Bai, Jonathan P. Winterstein, Alfredo Alexander-Katz, James Alexander Liddle, Caroline A. Ross
Transmission electron microscope (TEM) tomography was used to visualize the morphology and 3D connectivity of a lithographically-templated, self-assembled

Integration of TES microcalorimeters with microwave SQUID multiplexed readout.

Author(s)
Douglas A. Bennett, John A. Mates, Johnathon D. Gard, Andrew Hoover, Micheal Rabin, Carl D. Reintsema, Daniel R. Schmidt, Leila R. Vale, Joel N. Ullom
The demonstration of a microwave SQUID multiplexed readout of transition-edge sensor (TES) microcalorimeters has the potential to dramatically expand the scale

Entanglement-based quantum communication secured by nonlocal dispersion cancellation

Author(s)
Catherine Lee, Zheshen Zhang, Greg Steinbrecher, Hongchao Zhou, Jacob Mower, Tian Zhong, Ligong Wang, Rob Horansky, Varun Verma, Richard Mirin, Francesco Marsili, Matthew Shaw, Sae Woo Nam, Gregory Wornell, Franco N. Wong, Jeffrey Shapiro, Dirk Englund
The principles of quantum mechanics enable new applications that address unsolved problems in communications, computation, and precision measurement. Quantum
