Towards integrated superconducting detectors on lithium niobate waveguides

August 29, 2017
Author(s)
Jan P. Hoepker, Moritz Bartnick, Evan Meyer-Scott, Frederik Thiele, Stephan Krapick, Nicola Montaut, Matteo Santandrea, Harald Herrmann, Sebastian Lengeling, Raimund Ricken, Victor Quiring, Torsten Meier, Adriana Lita, Varun Verma, Thomas Gerrits, Sae Woo Nam, Christine Silberhorn, Tim J. Bartley
Superconducting detectors are now well-established tools for low-light optics, and in particular quantum optics, boasting high-efficiency, fast response and low noise. Similarly, lithium niobate is an important platform for integrated optics given its

Understanding the Major Update to NIST SP 800-63: Digital Identity Guidelines

August 29, 2017
Author(s)
Michael E. Garcia, Paul A. Grassi, Kristina G. Rigopoulos, Larry Feldman, Gregory A. Witte
This bulletin outlines the updates NIST recently made in its four-volume Special Publication (SP) 800-63, Digital Identity Guidelines, which provide agencies with technical guidelines regarding the digital authentication of users to federal networked

Effects of Powder Oxidation on Impact Toughness of Electron Beam Melt Ti-6Al-4V

August 25, 2017
Author(s)
Edward J. Garboczi, Enrico Lucon, William Grell, Z Loftus, Maciej Kumosa, E Solis-Ramos, Paul Predecki, E Clark
Powder quality in additive manufacturing (AM) electron beam melt (EBM) of Ti-6Al-4V components is crucial in determining the critical material properties of the end item. In this study, we report on the effect of powder oxidation on Charpy impact energy of

Pattern selection in ternary mushy layers

August 25, 2017
Author(s)
Daniel M. Anderson
We consider finite-amplitude convection in a mushy layer during the primary solidification of a ternary alloy. A previous linear theory identified, for the case of vanishing latent heat, solute rejection and background solidification, a direct mode of

An Analytical Solubility Model for Nitrogen-Methane-Ethane Ternary Mixtures

August 24, 2017
Author(s)
Jason Hartwig, Peter Meyerhofer, Ralph Lorenz, Eric Lemmon
Saturn's moon Titan has surface seas of liquid hydrocarbons and a thick, cold, nitrogen atmosphere, and is a target for future exploration. Critical to the design and operation of vehicles for this environment is knowledge of the amount of dissolved
