Suppression of Antiferromagnetic Spin Fluctuations in Superconducting Cr 0.8 Ru 0.2

October 25, 2018
Author(s)
M. Ramazanoglu, B. G. Ueland, D. K. Pratt, Leland Harriger, Jeffrey W. Lynn, G. Ehlers, G. E. Granroth, S. L. Bud'Ko, P. C. Canfield, D. Schlagel, A. I. Goldman, T. A. Lograsso, R. J. McQueeney
Although the precise mechanism is under, unconventional superconductivity (SC) is linked to the pairing of electrons by itinerant antiferromagnetic (AFM) spin fluctuations. Thus, unconventional SC often develops in magnetic metals on the cusp of static AFM

Time-Resolved Absorptance and Melt Pool Dynamics during Intense Laser Irradiation of a Metal

October 25, 2018
Author(s)
Brian J. Simonds, Jeffrey W. Sowards, Joshua A. Hadler, Erik A. Pfeif, Boris Wilthan, Jack R. Tanner, Paul A. Williams, John H. Lehman
Laser welding is a complex, dynamic process by which focused, high-intensity laser light is used to join two metallic surfaces and is being increasing deployed in a variety of industrial applications. Determining the time-dependent absorptance of the laser

Tracking the Progression of Anion Reorientational Behavior between a-Phase and b-Phase Alkali-Metal Silanides, MSIH 3 , by Quasielastic Neutron Scattering

October 25, 2018
Author(s)
Mirjana NMN Dimitrievska, Jean-Noel Chotard, Raphael Janot, Antonio Faraone, Wan Si Tang, Alexander V. Skripov, Terrence J. Udovic
Quasielastic neutron scattering (QENS) measurements over a wide range of resolutions were used to probe the reorientational behavior of the pyramidal SiH 3- anions in the mono-alkali silanides (MSiH 3, where M-K, Rb, and Cs) within the low-temperature

Fabrication and Testing of Photonic Thermometers

October 24, 2018
Author(s)
Nikolai Klimov, Zeeshan Ahmed
In recent years, a push for developing novel silicon photonic devices for telecommunications has generated a vast knowledge base that is now being leveraged for developing sophisticated photonic sensors. Silicon photonic sensors seek to exploit the strong

Predicting synthesizability

October 24, 2018
Author(s)
Albert Davydov, Ursula R. Kattner
Advancements in multiscale multi-physics computational materials design have led to accelerated discovery of advanced materials for energy, electronics and engineering applications. For most bulk materials synthesizing and processing procedures are

Recovering quantum gates from few average gate fidelities

October 24, 2018
Author(s)
Yi-Kai Liu, Ingo Roth, Richard Kueng, Shelby Kimmel, David Gross, Jens Eisert, Martin Kliesch
Characterizing quantum processes is a key task in and constitutes a challenge for the development of quantum technologies, especially at the noisy intermediate scale of today's devices. One method for characterizing processes is randomized benchmarking

Effects of Consumer Use Practices on Nanosilver Release from Commercially Available Food Contact Materials

October 23, 2018
Author(s)
Susana Addo Ntim, Samuel R. Norris, David Goodwin, Jens Breffke, Keana Scott, Li Piin Sung, Treye Thomas, Gregory O. Noonan
Migration evaluation involving nano-enabled food contact materials (FCMs) mostly focus on potential nanoparticle release from new unused products. This may not represent consumer use practices encountered by the FCMs in their lifecycle. In order to

SATE V Report: Ten Years of Static Analysis Tool Expositions

October 23, 2018
Author(s)
Aurelien M. Delaitre, Bertrand C. Stivalet, Paul E. Black, Vadim Okun, Terry S. Cohen, Athos Ribeiro
Software assurance has been the focus of the National Institute of Standards and Technology (NIST) Software Assurance Metrics and Tool Evaluation (SAMATE) team for many years.The Static Analysis Tool Exposition (SATE) is one of the team’s prominent

Transactive Energy Challenge Phase II Scenario

October 23, 2018
Author(s)
David G. Holmberg, Martin J. Burns, Steven T. Bushby, Avi M. Gopstein
The TE Challenge Phase II Scenario was developed in a multi-step process in collaboration with industry experts. The Scenario includes a common electric grid definition including attached loads and generators, weather, and reporting metrics which together

Flow fluctuations in wormlike micelle fluids

October 22, 2018
Author(s)
Paul NMN Salipante, Steven Meek, Steven D Hudson
We investigate the unstable flow of wormlike micelle solutions in pressure driven capillary flow, with a focus on the effect of entrance geometry on the fluid fluctuations. The flow is measured at different points in the capillary using particle image

Measurement and Modeling of Heterogeneous Chip-Scale Interconnections

October 22, 2018
Author(s)
Richard A. Chamberlin, Dylan F. Williams
We present precision scattering-parameter measurements of chip-to-chip connections in heterogeneous integrated circuits: indium phosphide or gallium nitride “chiplets” mounted on SiCMOS carrier chips. We demonstrate methodology, experimental results, and

Pulsed Laser Deposition Films from a Ba 2 FeMoO 6 Target onto SrTiO 3 [001]: Chemical and Magnetic Inhomogeneity

October 22, 2018
Author(s)
Daniel M. Pajerowski, Lisa J. Krayer, Brian Kirby, Brian B. Maranville, Julie Borchers, Kyeong-Won Kim, David P. Norton
We have used a combination of x-ray diffraction, atomic force microscopy, x-ray and neutron reflectivity, and x-ray photoelectron spectroscopy to investigate inhomogeneities within pulsed laser deposition, Ba 2FeMoO 6 films on SrTiO 3[001]. These results

3.5 GHz Federal Incumbent Protection Algorithms

October 21, 2018
Author(s)
Michael R. Souryal, Thao T. Nguyen, Nickolas J. LaSorte
The current standardized algorithm for U.S. federal incumbent protection in the 3.5 GHz band is sub-optimum in that it moves more commercial transmissions out of the protected channel than necessary, in most cases. This paper proposes a more efficient

Characterization of a Dual Josephson Impedance Bridge

October 21, 2018
Author(s)
Nathan Flowers-Jacobs, Blaise Jeanneret, Frederic Overney, Alain Rufenacht, Anna Fox, Paul Dresselhaus, Samuel P. Benz
This paper describes a dual Josephson impedance bridge capable of comparing any two impedances, that is, with any amplitude ratio and relative phase, over a wide range of frequency. A new, more compact, design has been achieved by mounting the two
