A pyroelectric detector-based method for low uncertainty spectral irradiance and radiance responsivity calibrations in the infrared using tunable lasers

April 4, 2022
Author(s)
Brian Alberding, John Woodward, Ping-Shine Shaw, Leonard Hanssen, Catherine Cooksey, Joseph P. Rice
The standard uncertainty of detector-based radiance and irradiance responsivity calibrations in the short-wave infrared (SWIR) traditionally has been limited to around 1 % or higher by the low spatial uniformity of detectors used to transfer the scale from

Generic character of charge and spin density waves in superconducting cuprates

Sangjun Lee, Edwin Huang, Thomas Johnson, Xuefei Guo, Ali Husain, Matteo Mitrano, Kannan Lu, Alexander Zakrzewski, Gilberto de la Pena, Yingying Peng, Hai Huang, Sang-Jun Lee, Hoyoung Jang, Jun-Sik Lee, Young Joe, W.Bertrand (Randy) Doriese, Paul Szypryt, Daniel Swetz, Songxue Chi, Adam Aczel, Gregory MacDougall, Steven Kivelson, Eduardo Fradkin, Peter Abbamonte
Charge density waves (CDWs) have been observed in nearly all families of copper-oxide superconductors. But the behavior of these phases across different families has been perplexing. In La-based cuprates, the CDW wavevector is an increasing function of

Disinfection of Respirators with Ultraviolet Radiation

Dianne L. Poster, Matthew Hardwick, C Cameron Miller, Michael A. Riley, W. W. Shanaka I. Rodrigo, Andras E. Vladar, John D. Wright, Christopher D. Zangmeister, Clarence Zarobila, Jeremy Starkweather, John Wynne, Jason Yilzarde
Data for interpreting virus inactivation on N95 face filtering respirators (FFRs) by ultraviolet (UV) radiation are important in developing UV strategies for N95 FFR disinfection and reuse for any situation, whether it be everyday practices, contingency

Models for an Ultraviolet-C Research and Development Consortium

March 25, 2022
Author(s)
Dianne L. Poster, C Cameron Miller, Yaw S. Obeng, John J. Kasianowicz, Michael T. Postek, Norman Horn, Troy Cowan, Richard Martinello
The development of an international, precompetitive, collaborative, ultraviolet (UV) research consortium is discussed as an opportunity to lay the groundwork for a new UV commercial industry and the supply chain to support this industry. History has

Recent Advances in Weyl Semimetal ( MnBi2Se4) and Axion Insulator (MnBi2Te4)

March 25, 2022
Author(s)
Sugata Chowdhury, Kevin Garrity, Francesca Tavazza
Extensive research is currently focused on 2D and 3D magnetic topological insulators (MTIs), as their many novel properties make them excellent candidates for applications in spintronics and quantum computing. Practical MTIs requires a combination of

Entropy transfer from a quantum particle to a classical coherent light field

March 23, 2022
Author(s)
John Bartolotta, Simon Jager, Jarrod Reilly, Matthew Norcia, James K. Thompson, Graeme Smith, Murray Holland
In the eld of light-matter interactions, it is often assumed that a classical light field that interacts with a quantum particle remains almost unchanged and thus contains nearly no information about the manipulated particles. To investigate the validity

Influence of Dimensionality on the Charge Density Wave Phase of 2H-TaSe2

March 23, 2022
Author(s)
Sugata Chowdhury, Albert Rigosi, Heather Hill, David B. Newell, Angela R. Hight Walker, Francesca Tavazza, Andrew Briggs
Metallic transition metal dichalcogenides like tantalum diselenide (TaSe2) exhibit exciting behaviors at low temperatures including the emergence of charge density wave (CDW) states. In this work, density functional theory (DFT) is used to classify the
