Coexistence of Ferromagnetic and Stripe-Type Antiferromagnetic Spin Fluctuations in YFe 2 Ge 2

May 31, 2019
Author(s)
Hongliang Wo, Qisi Wang, Yao Shen, Xiaowen Zhang, Yiqing Hao, Yu Feng, Shoudong Shen, Zheng He, Bingying Pan, Wenbin Wang, K. Nakajima, S. Ohira-Kawamura, P. Steffens, M. Boehm, K. Schmalzl, T. R. Forrest, M. Matsuda, Yang Zhao, Jeffrey W. Lynn, Zhiping Yin, Jun Zhao
We report neutron scattering measurments of single-crystalline YFe 2Ge 2 in the normal state, which has the same crystal structure to the 122 family of iron pnictide superconductors. YFe 2Ge 2 does not exhibit long range magnetic order, but exhibits strong

Quantum gate teleportation between separated zones of a trapped-ion processor

May 31, 2019

The overall aim of the annual National Oceanic and Atmospheric Administration (NOAA) dedicated Joint Polar Satellite System (JPSS) Visible Infrared Imaging Radiometer Suite (VIIRS) ocean color calibration/validation cruises is to support improvements in

Structure and Function in Antimicrobial Piscidins: Histidine Position, Directionality of Membrane Insertion, and pH-Dependent Permeabilization

May 30, 2019
Author(s)
Mihaela Mihailescu, Mirco Sorci, Jolita Seckute, Vitalii I. Silin, Janet Hammer, B. Scott Perrin, Jorge Hernandez, Nedzada Smajic, Akritee Shrestha, Kimberly Bogadardus, Alexander Greenwood, Riqiang Fu, Jack Blazyk, Richard W. Pastor, Linda Nicholson, Georges Belfort, Myriam Cotten
Piscidins are histidine-enriched antimicrobial peptides that interact with lipid bilayers as amphipathic alpha-helices. Their activity at acidic and basic pH in vivo makes them promising templates for biomedical applications. This study focuses on p1 and

Calibration Procedures for Weights and Measures Laboratories

May 29, 2019
Author(s)
Georgia L. Harris
This publication contains standard operating procedures for calibrations that were not previously published in other NIST Office of Weights and Measures publications and are included here in support of weights and measures laboratory program requirements

Single-scan acquisition of multiple multidimensional spectra

May 29, 2019
Author(s)
Travis M. Autry, Galan Moody, James M. Fraser, Corey A. McDonald, Richard P. Mirin, Kevin L. Silverman
Multidimensional coherent spectroscopy is a powerful tool for understanding the ultrafast dynamics of complex quantum systems. To fully characterize the nonlinear optical response of a system, multiple pulse sequences must be recorded and quantitatively

Magnetic Structure and Spin Waves in the Frustrated Ferro-Antiferro Magnet Pb 2 VO(PO 4 ) 2

S. Bettler, F. Landolt, O. M. Aksoy, Z. Yan, S. Gvasaliya, Yiming Qiu, E. Ressouche, K. Beauvois, S. Raymond, A. N. Ponomaryov, S. A. Zvyagin, A. Zheludev
Single crystal neutron diffraction, inelastic neutron scattering and electron spin resonance experiments are used to study the magnetic structure and spin waves in Pb 2VO(PO 4) 2, a prototypical layered S =1/2 ferromagnet with frustrating next nearest

Graphical Methods in Device-Independent Quantum Cryptography

May 27, 2019
Author(s)
Spencer J. Breiner, Carl A. Miller, Neil J. Ross
We introduce a framework for providing graphical security proofs for quantum cryptography using the methods of categorical quantum mechanics. We are optimistic that this approach will make some of the highly complex proofs in quantum cryptography more
