Crystalline Quantum Circuits

July 31, 2023
Author(s)
Grace Sommers, David Huse, Michael Gullans
Random quantum circuits continue to inspire a wide range of applications in quantum information science, while remaining analytically tractable through probabilistic methods. Motivated by the need for deterministic circuits with similar applications, we

Disorder-Induced Excitation Continuum in a Spin-1/2 Cobaltate on a Triangular Lattice

July 31, 2023
Author(s)
Bin Gao, Tong Chen, Chien-Lung Huang, Yiming Qiu, Guangyong Xu, Jesse Liebman, Lebing Chen, Matthew B. Stone, Erxi Feng, Huibo Cao, Xiaoping Wang, Xianghan Xu, Sang-Wook Cheong, Stephen Winter, Pengcheng Dai
A spin-1/2 triangular-lattice antiferromagnet is a prototypical frustrated quantum magnet, which exhibits remarkable quantum many-body effects that arise from the synergy between geometric spin frustration and quantum fluctuations. It can host quantum

Lightshow: a Python package for writing computational x-ray absorption spectroscopy input files

July 29, 2023
Author(s)
Matthew Carbone, Fanchen Meng, Christian Vorwerk, Benedikt Mauer, Fabian Peschel, Xiaohui Qu, Eli Stavitski, Claudia Draxl, John Vinson, Deyu Lu
Spectroscopy simulations are a critical tool for the interpretation of experiment, the development of new theoretical understanding, and fast screening of new molecules and materials. Systematically setting up input files for different simulation codes and

A review of thermal exposure and fire spread mechanisms in Large Outdoor Fires and the Built Environment

July 28, 2023
Author(s)
Alex Filkov, Virginie Tihay-Felicelli, Nima Masoudvaziri, David Rush, Andres Valencia, Yu Wang, David Blunck, Mario Valero, Kamila Kempna, Jeruzalemska Jan Smolka, Jacques De Beer, Zakary Campbell-Lochrie, Felipe Centeno, Muhammad Asim Ibrahim Stuvaregatan, Calisa Katiuscia Lemmertz, Wai Cheong Tam
Due to socio-economic and climatic changes around the world, large outdoor fires in the built environment have become one of the global issues that threaten billions of people. The devastating effects of them are indicative of weaknesses in existing

Design and Implementation of a Closed-Loop Mobile Manipulator Control System

July 28, 2023
Author(s)
Omar Aboul-Enein, Ya-Shian Li-Baboud, Roger Bostelman, Ann Virts
Mobile manipulators, which integrate a robotic manipulator with an automatic--autonomous mobile base, have the potential to augment automation by combining the capability of navigation with complex manipulation to support unstructured and dynamic

Non-nulling Protocols for Fast, Accurate, 3-D Velocity Measurements in Stacks

July 28, 2023
Author(s)
Iosif Isaakovich Shinder, Aaron Johnson, James Filla, Vladimir B. Khromchenko, Michael R. Moldover, Joey Boyd, John D. Wright, John R. Stoup
We present protocols for making fast, accurate, 3-D velocity measurements in the stacks of coal-fired power plants. The measurements are traceable to internationally-recognized standards; therefore, they provide a rigorous basis for measuring and/or

November 2022 NIST Premise Plumbing Research Workshop: Summary and Findings

July 28, 2023
Author(s)
Andrew K. Persily, Marylia Duarte Batista, William M. Healy, Mark A. Kedzierski, Lingnan Lin, Natascha S. Milesi-Ferretti, Tania Ullah, David A. Yashar, Stephen Zimmerman
Premise plumbing systems need to meet a range of performance goals including occupant health and comfort, energy and water efficiency, and reduced environmental impacts. Pressures to improve water efficiency and building water quality, combined with the

Redundant Ballistic Chronograph Configuration for Body Armor Testing

July 28, 2023
Author(s)
Michael A. Riley, Nicholas G. Paulter Jr., Dwight D. Barry
A new configuration of the light screen pairs used in a redundant ballistic chronograph is described. This configuration complies with current ASTM International and National Institute of Justice requirements for measuring the ballistic performance of body

Testing dielectric slab mode excitation, non-rectangular conductor profiles and edge roughness as sources of additional loss in mmWave transmission lines

July 28, 2023
Author(s)
Florian Bergmann, Nicholas Jungwirth, Bryan Bosworth, Jason Killgore, Eric Marksz, Tomasz Karpisz, Meagan Papac, Anna Osella, Lucas Enright, Christian Long, Nathan Orloff
Losses in mmWave transmission lines often exceed first-principles predictions based on measurements of dc resistivity and the nominal conductor geometry. In our case, we observed an additional distributed resistance of coplanar waveguides on DyScO3

The BETTER Cross-Language Information Retrieval Datasets

July 27, 2023
Author(s)
Ian Soboroff
The IARPA BETTER (Better Extraction from Text Through Enhanced Retrieval) program held three evaluations of information retrieval (IR) and information extraction (IE). For both tasks, the only training data available was in English, but systems had to

CO Reduction on Single-atom Copper

July 26, 2023
Author(s)
Yuxuan Wang, Hao Shen, Bin Xue, Boyang Li, Nicole Libretto, Han Zong, Wenjun Xie, Ziyuan Li, Guangye Zhou, Jeffrey Vetik, Jeffrey T. Miller, Guofeng Wang, Chao Wang, David Raciti

Quantum Entropic Effects in the Liquid Viscosities of Hydrogen, Deuterium, and Neon

July 26, 2023
Author(s)
Ian Bell, Jacob Leachman, Albert Rigosi, Heather Hill
The extreme conditions have limited the availability and accuracy of experimental thermophys- ical property measurements for cryogens, particularly transport properties. Traditional scaling techniques such as corresponding states theory have long been

A Deep Learning Framework for Industrial Wireless Networks

July 25, 2023
Author(s)
Mohamed Hany, Rick Candell
In this report, we introduce a framework to analyze, monitor, and identify the state of industrial wireless networks and their impact on industrial use cases. This framework is based on a deep learning approach for modeling the interactions between the
