Materials loss measurements using superconducting microwave resonators

June 9, 2020
Author(s)
Corey Rae H. McRae, Haozhi Wang, Jiansong Gao, Michael R. Vissers, Teresa Brecht, A Dunsworth, David P. Pappas, J. Mutus
The performance of superconducting circuits for quantum computing is limited by materials losses. In particular, coherence times are typically bounded by two-level system (TLS) losses at single photon powers and millikelvin temperatures. The identification

Realization of a stroboscopic optical lattice for cold atoms with subwavelength spacing

June 9, 2020
Author(s)
TC Tsui, Yang Wang, Sarthak Subhankar, James V. Porto, Steve Rolston
Optical lattices are typically created via the ac-Stark shift, which are limited by diffraction to periodicities ≥ λ/2, where λ is the wavelength of light used to create them. Lattices with smaller periodicities may be useful for many-body physics with

Response Bias of Electrical Cable Coatings at Fire Conditions (REBECCA-FIRE)

June 9, 2020
Author(s)
Kevin B. McGrattan, Edward J. Hnetkovsky, Scott D. Bareham, Michael J. Selepak, Morgan Bruns
This report contains results of a multi-year experimental program called REBECCA-FIRE (Response Bias of Electrical Cable Coatings at Fire Conditions). Volume 2 of the three volume report focuses on the burning behavior of electrical cables that are

Spectroscopic analysis of N-intrashell transitions in Rb-like to Ni-like Yb ions

June 9, 2020
Author(s)
Dipti Goyal, R. Silwal, Joan M. Dreiling, Samuel C. Sanders, Endre A. Takacs, Yuri Ralchenko
Extreme ultraviolet spectra of highly-charged ytterbium ions produced in an electron beam ion trap at National Institute of Standards and Technology were observed with a at- eld grazing incidence spectrometer in the wavelength region of about 4 nm to 20 nm

Structural basis for oligoclonal T cell recognition of a shared p53 cancer neoantigen

June 9, 2020
Author(s)
David Travis Gallagher, Roy A. Mariuzza, Brian G. Pierce, Daichao Wu, Ragul Gowthaman
Abstract Adoptive cell therapy (ACT) with tumor-specific T cells can mediate cancer regression. The main target of tumor-specific T cells are neoantigens arising from mutations in self-proteins. Although the majority of cancer neoantigens are unique to

NVLAP Carpet and Carpet Cushion

June 8, 2020
Author(s)
Timothy W. Rasinski
NIST Handbook 150-6 specifies the technical requirements and provides guidance for the accreditation of laboratories under the NVLAP Carpet and Carpet Cushion Laboratory Accreditation Program (CCC Program).

Room-temperature skyrmions in strain-engineered FeGe thin films

June 8, 2020
Author(s)
Sujan Budhathoki, Arjun Sapkota, Ka M. Law, Smriti Ranjit, Bhuwan Nepal, Brian Hoskins, Arashdeep S. Thind, Albina Y. Borisevich, Michelle E. Jamer, Travis J. Anderson, Andrew D. Koehler, Karl D. Hobart, Gregory M. Stephen, Don Heiman, Tim Mewes, Rohan Mishra, James C. Gallagher, Adam J. Hauser
Skyrmion electronics hold great promise for low energy consumption and stable high information density, and stabilization of Skyrmion lattice (SkX) phase at or above room temperature is greatly desired for practical use. Topological Hall Effect can be used

Color, Structure, and Rheology of a Diblock Bottlebrush Copolymer Solution

June 7, 2020
Author(s)
Matthew A. Wade, Dylan Walsh, Johnny Ching-Wei Lee, Elizabeth Kelley, Kathleen Weigandt, Damien Guironnet, Simon A. Rogers
A structure-property-process relation is established for a diblock bottlebrush copolymer solution, through a combination of rheo-neutron scattering, imaging, and rheological measurements. Polylactic acid-b-polystyrene diblock bottlebrush copolymers were

Mid-Infrared Dual Frequency Comb Spectroscopy for Combustion Analysisin the 2.8 to 5 micron Spectral Region

June 7, 2020
Author(s)
Ian Coddington, Nathan Newbury, Greg Rieker, Amanda S. Makowiecki, Daniel Herman, Nazanin Hoghooghi, Elizabeth F. Strong, Gabriel Ycas, Fabrizio Giorgetta, Ryan Cole, Caelan Lapointe, Jeff Glusman, John Daily, Peter E. Hamlington
We demonstrate the application of mode-locked mid-infrared dual frequency comb spectroscopy for combustion analysis. With two settings of the same dual-comb system, the measurement spans 1500 cm-1 (2.8 to 5 microns) with 0.0067 cm-1 (200 MHz) point spacing

Evaluating Uncertainty of Microwave Calibrations with Regression Residuals

June 6, 2020
Author(s)
Dylan F. Williams, Benjamin F. Jamroz, Jake D. Rezac, Robert D. Jones
We present a sensitivity-analysis and a Monte-Carlo algorithm for evaluating the uncertainty of multivariate microwave calibration models with regression residuals. We then use synthetic data to verify the performance of the algorithms and explore their

{A high-throughput structural and electrochemical study of metallic glass formation in Ni-Ti-Al

June 4, 2020
Author(s)
Howard L. Joress, Brian L. DeCost, Suchismita Sarker, Trevor M. Braun, Logan T. Ward, Kevin Laws, Apurva Mehta, Jason R. Hattrick-Simpers
Based on a set of machine learning predictions of glass formation in the Ni-Ti-Al system, we have undertaken a high-throughput experimental study of that system. We utilized rapid synthesis followed by high- throughput structural and electrochemical

Blind Measurement of Receiver System Noise

June 4, 2020
Author(s)
Dan Kuester, Adam Wunderlich, Duncan McGillivray, Dazhen Gu, Audrey Puls
Tightly packaged receive systems pose a challenge for noise measurements. The only available receiver outputs are often user data: link benchmark or diagnostic information that can be scavenged with software. These could include data rate benchmark, self
