Anomalous spin-orbit torques in magnetic single-layer films

July 22, 2019
Author(s)
Wenrui Wang, Tao Wang, Vivek P. Amin, Yang Wang, Anil Radhakrishna, Angie Davidson, Shane Allen, Thomas J. Silva, Hendrik Ohldag, Davor Balzar, Barry L. Zink, Paul M. Haney, John Xiao, D.G. Cahill, Virginia O. Lorenz, Xin Fan
Spin-orbit interaction (SOI) couples charge and spin transport, enabling electrical control of magnetization, the foundation of next-generation spintronic devices. A quint essential example of SOI-induced transport is the anomalous Hall effect (AHE), first

Developing Next-generation Brain Sensing Technologies - A Review

July 22, 2019
Author(s)
Jacob T. Robinson, Eric Pohlmeyer, Malte C. Gather, Caleb Kemere, John Kitching, George G. Malliaras, Adam Marblestone, Kenneth L. Shepard, Thomas Stieglitz, Chong Xie
Advances in sensing technology raise the possibility of creating neural interfaces that can more effectively restore or repair neural function and reveal fundamental properties of neural information processing. To realize the potential of these

Materials Science in the AI age: high-throughput library generation, machine learning and a pathway from correlations to the underpinning physics

July 22, 2019
Author(s)
Kamal Choudhary, Aaron G. Kusne, Francesca M. Tavazza, Jason R. Hattrick-Simpers, Rama K. Vasudevan, Apurva Mehta, Ryan Smith, Lukas Vlcek, Sergei V. Kalinin, Maxim Ziatdinov
The use of advanced data analytics, statistical and machine learning approaches (‘AI’) to materials science has experienced a renaissance, driven by advances in computer sciences, availability and access of software and hardware, and a growing realization

Precision, Tunable Deuterated Polyethylene via Polyhomologation

July 22, 2019
Author(s)
Wesley Farrell, Sara Orski, Anthony Kotula, Kathryn Beers, Daniel Baugh
Polyhomologation (also known as "C1 polymerization") of a deuterated ylide has been performed, which yields linear polyethylene of high deuterium content. Copolymerization with the protonated analog allows for the preparation of sta-tistical copolymers, in

Quantum-enhanced sensing of a mechanical oscillator

July 22, 2019
Author(s)
Katherine C. McCormick, Jonas Keller, Shaun C. Burd, David J. Wineland, Andrew C. Wilson, Dietrich Leibfried
The use of special quantum states in interferometry with bosons to achieve sensitivities below the limits established by classical-like coherent dates back decades and has enjoyed immense success since its inception. Squeezed states, number states, and cat

PROBABILITY OF DETECTION OF X-RAY COMPUTED TOMOGRAPHY OF ADDITIVE MANUFACTURING DEFECTS

July 19, 2019
Author(s)
Felix H. Kim, Adam L. Pintar, Jason C. Fox, Jared B. Tarr, M A. Donmez, Anne-Fran?oise Obaton
A methodology to determine probability of detection (POD) of X-ray Computed Tomography (XCT) was developed using Additive Manufacturing defects. A signal response POD analysis (a^ vs a) was used, where both signal response (a^) and true defect size (a)

Quantum interference enables constant-time quantum information processing

July 19, 2019
Author(s)
Thomas Gerrits, Sae Woo Nam, Adriana E. Lita, M. Stobinska, A. Buraczewski, M. Moore, W.R. Clements, J.J. Renema, W.S. Kolthammer, A. Eckstein, I.A. Walmsley
It is an open question how fast information processing can be performed and whether quantum effects can speed up the best existing solutions. Signal extraction, analysis, and compression in diagnostics, astronomy, chemistry, and broadcasting build on the

Sensing Fabrication Errors in Diffraction Gratings using High Dynamic Range Imaging

July 19, 2019
Author(s)
Sofia C. Corzo Garcia, Johannes A. Soons, Ulf Griesmann
We describe the design of a simple instrument for the identification and characterization of fabrication errors in diffraction gratings. The instrument uses an uncooled charge-coupled device (CCD) camera and a high dynamic range imaging process to detect

Integrating four-dimensional ontology and systems requirements modelling

July 18, 2019
Author(s)
Conrad E. Bock, Charles Galey
Ontology has many applications to engineering but is not easily taken up by engineers. For example, specifying products in space and time together (four dimensions) enables more reliable modelling and analysis, but this work is primarily ontological and

Practical Cryptanalysis of k-ary C*

July 18, 2019
Author(s)
Daniel C. Smith-Tone
Recently, an article by Felke appeared in Cryptography and Communications discussing the security of biquadratic $C^*$ and a further generalization, k-ary $C^*$. The article derives lower bounds for the complexity of an algebraic attack, directly inverting

A Cold-Atom Beam Clock, based on Coherent Population Trapping

July 17, 2019
Author(s)
John D. Elgin, Thomas P. Heavner, John E. Kitching, Elizabeth A. Donley, Jayson Denney, Evan Salim
We present results from a novel atomic clock which employs a beam of cold 87 Rb atoms and spatially separated (Ramsey) coherent population trapping interrogation of the hyperfine clock transition at 6.834 GHz. The cold atomic beam is generated through the

Active protection of a superconducting qubit with an interferometric Josephson isolator

Author(s)
Baleegh Abdo, Nicholas T. Bronn, Oblesh Jinka, Salvatore B. Olivadese, Antonio D. Corcoles, Vivekananda P. Adiga, Markus Brink, Russell Lake, Xian Wu, David P. Pappas, Jerry M. Chow
Nonreciprocal microwave devices play critical roles in high-fidelity, quantum-nondemolition (QND) measurement schemes. They impose unidirectional routing of readout signals and protect the quantum systems from unwanted noise originated by the output chain

Quantifying Macroeconomic Resilience Dividends in Cedar Rapids

July 17, 2019
Author(s)
Juan F. Fung, Jennifer F. Helgeson, Cheyney M. O'Fallon, David H. Webb, Harvey Cutler
Cedar Rapids, Iowa offers a unique case study in planning for increased resilience. In 2008, Cedar Rapids experienced severe flooding. Rather than simply rebuilding, the city of Cedar Rapids is investing in a resilient flood control system, as well as in
