Probing Intrinsic Magnetization Dynamics of the Y3Fe5O12/Bi2Te3 Interface at Low Temperature

July 23, 2024
Author(s)
A. R. Will-Cole, Valeria Lauter, Alexander Grutter, Carsten Dubs, David Lidsky, Morris Lindner, Timmy Reimann, Nirjhar Bhattacharjee, Tzu-Ming Lu, Peter Sharma, Nichole Valdez, Charles Pearce, Todd Monson, Matthew Matzelle, Arun Bansil, Don Heiman, Nian Sun
Topological insulator–magnetic insulator (TI–MI) heterostructures hold significant promise in the field of spintronics, offering the potential for manipulating magnetization through topological surface state–enabled spin-orbit torque. However, many TI–MI

Detailed Dynamics of a Moving Magnetic Skyrmion Lattice in MnSi Observed Small-Angle Neutron Scattering under an Alternating Electric Current Flow

Author(s)
D. Okuyama, M. Bleuel, Qiang Ye, Jeffery Krzywon, N. Nagaosa, A. Kikkawa, Y. Taguchi, Y. Tokura, J. Reim, Y. Nambu, T. Sato
Lattice formation of swirling textures is ubiquitous in solid-state materials, such as a magnetic skyrmion lattice in chiral magnets. In the magnetic skyrmion lattices, their moving states and dynamics under external perturbations are still unrevealed

Intertwined Charge and Spin Density Waves in a Topological Kagome Material

July 22, 2024
Author(s)
Y. Chen, Jonathan N. Gaudet, G. Marcus, T. Nomoto, T. Chen, T. Tomita, M. Ikhlas, H. Suzuki, Yang Zhao, Wangchun Chen, J. Strempfer, R. Arita, S. Nakatsuji, Collin L. Broholm
Using neutrons and x rays we show the topological kagome antiferromagnet Mn3Sn for T 285 K forms a homogeneous spin and charge ordered state comprising a longitudinally polarized spin density wave with wave vector kβ = kβ ˆc, a helical modulated version

Quantum Lego Expansion Pack: Enumerators from Tensor Networks

July 22, 2024
Author(s)
ChunJun Cao, Michael Gullans, Brad Lackey, Zitao Wang
We provide the first tensor network method for computing quantum weight enumerator polynomials in the most general form. As a corollary, if a quantum code has a known tensor network construction of its encoding map, our method produces an algorithm that

Reverse Separation of Carbon Dioxide and Acetylene in Two Isostructural Copper Pyridine-Carboxylate Frameworks

July 21, 2024
Author(s)
Jing-Hong Li, You-Wei Gan, Jun-Xian Chen, Rui-Biao Lin, Yisi Yang, Hui Wu, Wei Zhou, Banglin Chen, Xiao-Ming Chen
Separating acetylene from carbon dioxide is important but highly challenging due to their similar molecular shapes and physical properties. Adsorptive separation of carbon dioxide from acetylene can directly produce pure acetylene but is hardly realized

Far-UVC: The impact of optical filters on real-world deployment

July 20, 2024
Author(s)
C Cameron Miller, Ewan Eadie, Paul O'Mahoney, Sally Ibbotson, Kenneth Wood
In 2015, a study showed that Krypton-Chloride (KrCl) excimer lamps could induce erythema and basal layer DNA damage in human skin. Later studies found that filtering out longer wavelength emissions from these lamps resulted in no acute skin effects

Food Nutrition and Safety Measurements Quality Assurance Program: Exercise 2 Final Report

July 19, 2024
Author(s)
Melissa M. Phillips, Colleen E. Bryan Sallee, Carolyn Burdette, Steven J. Christopher
The Food Nutrition and Safety Measurements Quality Assurance Program (FNSQAP) was launched in 2021. FNSQAP was established to assist laboratories in the development and validation of new analytical methods, in improving the quality of their analytical

On-Wafer Capacitor Characterization Including Uncertainty Estimates Up to 1.0 THz

July 19, 2024
Author(s)
Robert Jones, Jerome Cheron, Benjamin Jamroz, Dylan Williams, Ari Feldman, Peter Aaen, Christian Long, Nathan Orloff
In this article we extract the capacitance of shunt and series metal-insulator-metal capacitors from on-wafer S-parameter measurements in the WR1.0 waveguide band. We verify consistency of the measured devices in two different state-of-the-art terahertz

The NIST Wildland-Urban Interface Fire Case Study Approach and Outlook

July 19, 2024
Author(s)
Eric Link
Wildland-urban interface (WUI) fires are a threat to thousands of communities in the United States. Thousands of structures are destroyed, and thousands of lives are threatened or upended by fires every year. There are valuable lessons to be learned from

Effects of Dimensionality on the Electronic Structure of Ruddlesden-Popper Chromates Srn+1CrnO3n+1

Spencer Doyle, Lerato Takana, Margaret Anderson, Dan Segedin, Hesham El-Sherif, Charles Brooks, Xiaoping Wang, Padraic Shafer, Alpha N'Diaye, Ismail El Baggari, William Ratcliff, Andres Cano, Quintin Meier, Julia Mundy
Transition-metal oxides host a wide variety of electronic phenomena that can be significantly influenced by the effective dimensionality of the system under consideration. These include charge, spin, and orbital orderings, as well as unconventional

Assessing the Benefits and Risks of Quantum Computers

July 17, 2024
Author(s)
Travis Scholten, Carl Williams, Dustin Moody, Michele Mosca, William Hurley, William J. Zeng, Matthias Troyer, Jay Gambetta
Quantum computing is an emerging technology with potentially far-reaching implications for national prosperity and security. Understanding the timeframes over which economic benefits and national security risks may manifest themselves is vital for ensuring

Database-assisted-design facilitating performance-based tall building design

July 17, 2024
Author(s)
Daniel Rhee, Sophie Sisson, Brian Carman, Mehedy Mashnad, DongHun Yeo
In recent years, wind design, particularly for high-rise buildings, has seen a paradigm shift from a code-based descriptive method to a more specific performance-objective-based design. This new approach, known as the Performance-Based Wind Design (PBWD)

Spin Echo Small-Angle Neutron Scattering using Superconducting Magnetic Wollaston Prisms

July 17, 2024
Author(s)
Fumiaki Funama, Caitlyn Wolf, Kathleen Weigandt, Jiazhou Shen, Steven Parnell, Fankang Li
We show the implementation of superconducting magnetic Wollaston prisms for spin echo small-angle neutron scattering. Two calibration methods for the spin echo length are presented: one utilizing spin echo modulated small-angle neutron scattering and the
