Intrinsically accurate sensing with an optomechanical accelerometer

May 18, 2022
Author(s)
Benjamin Reschovsky, David Long, Feng Zhou, Yiliang Bao, Richard A. Allen, Jason J. Gorman, Thomas W. LeBrun
We demonstrate a microfabricated optomechanical accelerometer that is capable of percent-level accuracy without external calibration. To achieve this capability, we use a mechanical model of the device behavior that can be characterized by the thermal

Quantifying Receiver Nonlinearities in VNA Measurements for the WR-15 Waveguide Band

March 15, 2022
Author(s)
Angela Stelson, Aaron Hagerstrom, Jeffrey Jargon, Chris Long
Scattering (S-) parameters are fundamental to numerous microwave quantities including antenna factors, microwave power, and phase. The uncertainty in S-parameter measurements is influenced by the test setup, including instrument noise, drift, position of

VEMOS: A GUI for Evaluation of Similarity Metrics on Complex Data Sets

June 7, 2021
Author(s)
Gunay Dogan, Eve Fleisig
Similarity and dissimilarity metrics are a fundamental component of many tasks requiring the analysis and comparison of complex, often visual data. Applications from deep learning to forensics require ways to effectively identify images, find clusters or

Exchange Bias Switching in an Antiferromagnet/Ferromagnet Bilayer Driven by Spin-Orbit Torque

December 1, 2020
Author(s)
Shouzhong Peng, Daoqian Zhu, Weixiang Li, Hao Wu, Alexander Grutter, Dustin A. Gilbert, Jiaqi Lu, Danrong Xiong, Wenlong Cai, Padraic Shafer, Kang L. Wang, Weisheng Zhao
Electrical manipulation of exchange bias and magnetization in antiferromagnet/ferromagnet thin films has been of great interest in recent years. Here, we experimentally demonstrate current-induced switching of exchange bias in perpendicularly magnetized

Revealing thermodynamics of DNA origami folding via affine transformations

June 4, 2020
Author(s)
Jacob M. Majikes, Paul N. Patrone, Daniel R. Schiffels, Michael P. Zwolak, Anthony J. Kearsley, Samuel P. Forry, James A. Liddle
Structural DNA nanotechnology, as exemplified by DNA origami, has enabled the design and construction of molecularly precise objects for a myriad of applications. However, limitations in imaging, and other characterization approaches, make a quantitative

Long-Range Magnetic Order in Hydroxide-Layer-Doped (Li 1-x-y Fe x Mn y OD)FeSe

March 11, 2020
Author(s)
Brandon Wilfong, Xiuquan Zhou, Huafei Zheng, Navneeth Babra, Craig Brown, Jeffrey W. Lynn, Keith M. Taddei, Johnpierre Paglione, Efrain E. Rodriguez
The (Li 1-xFe xOH)FeSe superconductor has been suspected to exhibit long-range magnetic ordering due to Fe substitution in the LiOH layer. However, no direct observation such as magnetic reflection from neutron diffraction has be reported. Here, we use a
