Ba8Cu16As30: A cationic-framework clathrate-I arsenide

August 10, 2018
Author(s)
Kaya Wei, Artem R. Khabibullin, Dean Hobbis, Winnie Wong-Ng, Tieyan Chang, SuYin G. Wang, Igor Levin, Yu-Sheng Chen, Lilia M. Woods, George S. Nolas
Single crystals of clathrate-I Ba8Cu16As30 have been synthesized, and their structure and electronic properties deter-mined using synchrotron-based X-ray diffraction and first principles calculations. The structure is confirmed to be cubic and defined by a

Manufacturing USA Annual Report, FY 2017

August 10, 2018
Author(s)
Michael F. Molnar
As required by the Revitalize American Manufacturing and Innovation Act of 2014, this report describes the major accomplishments of Manufacturing USA in FY17. This report documents progresss in meeting the goals of the program as stated in its Strategic

Federal Office of Research and Technology Applications Survey Results

August 9, 2018
Author(s)
Nicole K. Gingrich
This publication serves as a formal reporting of the data presented at the 2017 Federal Laboratory Consortium’s National Meeting. It presents summary data collected through a survey conducted by NIST in conjunction with the Interagency Working Group on

Infrared Astronomical Spectroscopy and Radial Velocity Measurements with Precision Below 10 cm/s

August 9, 2018
Author(s)
Andrew J. Metcalf, Tyler Anderson, Chad F. Bender, Wesley Brand, David Carlson, Scott Diddams, Connor Fredrick, S. Halverson, Daniel D. Hickstein, Fred Hearty, Jeffrey M. Jennings, Shubham Kanodia, Kyle Kaplan, Emily Lubar, Suvrath Mahadevan, Andrew Monson, Joe P. Ninan, Colin Nitroy, Scott Papp, L. Ramsey, Paul Robertson, Arpita Roy, Christian Schwab, Kartik Srinivasan, Gudmundur Stefansson, Ryan C. Terrien
We detail the first infrared precision astronomical spectroscopy results from the combination of an electro-optic laser frequency comb and the Habitable Zone Planet Finder spectrograph at the 10 m Hobby-Eberly telescope.

An electro-optic ultrafast light source with sub-cycle stability

August 8, 2018
Author(s)
David R. Carlson, Daniel D. Hickstein, Wei Zhang, Andrew J. Metcalf, Franklyn J. Quinlan, Scott A. Diddams, Scott B. Papp
Optical frequency combs can produce femtosecond light pulses with sub-cycle precision, and are typically made by relying on the intrinsic stability of mode-locked lasers. Now, by carving a continuous-wave laser into pulses via electro-optic modulation (EOM

Spin Waves in Detwinned BaFe 2 As 2

August 8, 2018
Author(s)
Xingye Lu, Daniel D. Scherer, David W. Tam, Wenliang Zhang, Rui Zhang, Huiqian Luo, Leland Harriger, H. C. Walker, D.T. Adroja, Brian M. Andersen, Pengcheng Dai

Thermal and Nonlinear Dissipative-Soliton Dynamics in Kerr Microresonator Frequency Combs

August 8, 2018
Author(s)
Jordan R. Stone, Travis Briles, Tara E. Drake, Daryl T. Spencer, David R. Carlson, Scott A. Diddams, Scott B. Papp
We report on radiofrequency techniques to reliably generate and control dissipative-Kerr- soliton microresonator frequency combs. Since the pump-laser frequency detuning to the resonator primarily determines the soliton dynamics, we devise an offset Pound

Application of the Complex Kohn Variational Method to Attosecond Spectroscopy

August 6, 2018
Author(s)
Barry I. Schneider, Nicholas Douguet, Luca Argenti
The complex Kohn (CK) variational method is extended to compute light-driven electronic transitions between continuum wavefunctions in atomic and molecular systems. This development enables the study of multiphoton processes in the perturbative regime for

Micromachined force balance for optical power measurement by radiation pressure sensing

August 6, 2018
Author(s)
Ivan Ryger, Alexandra B. Artusio-Glimpse, Paul A. Williams, Nathan A. Tomlin, Michelle S. Stephens, Matthew T. Spidell, Kyle A. Rogers, John H. Lehman
We introduce a micromachined force scale for laser power measurement by means of radiation pressure sensing. With this technique, the measured laser light is not absorbed and can be utilized while being measured. We employ silicon micromachining technology

Nanoscale partitioning of Paclitaxel in Hybrid Lipid-Polymer Membranes

August 6, 2018
Author(s)
Mohit Tuteja, Minjee Kang, Cecilia Leal, Andrea Centrone
Paclitaxel is a powerful drug against restenosis and many forms of cancer. However, its clinical application hinges on the ability to achieve suitable stabilized drug concentrations in an aqueous suspension while hindering drug crystallization. To engineer

Unsupervised phase mapping of X-ray diffraction data by nonnegative matrix factorization integrated with custom clustering

August 6, 2018
Author(s)
Valentin Stanev, Velimir Vesselinov, Aaron Gilad Kusne, Graham Antoszewski, Ichiro Takeuchi, Boian Alexandrov
Analyzing large X-ray diffraction (XRD) datasets is a key step in high-throughput mapping of the compositional phase diagrams of combinatorial materials libraries. Optimizing and automating this task can help accelerate the process of discovery of

A 300-mK Test Bed for Rapid Characterization of Microwave SQUID Multiplexing Circuits

August 3, 2018
Author(s)
Abigail L. Wessels, Daniel T. Becker, Douglas A. Bennett, Johnathon D. Gard, Johannes Hubmayr, Norman Jarosik, Vincent Y. Kotsubo, John A. Mates, Joel N. Ullom
Microwave SQUID multiplexing is a promising technique for multiplexing large arrays of transition edge sensors. A major bottleneck in the development and distribution of microwave SQUID multiplexer chips occurs in the time-intensive design testing and
