A Strategy for Handling Aberration in Spherical Neutron Polarimetry

December 11, 2019
Author(s)
Jacob Tosado, Wangchun Chen, Efrain E. Rodriguez
We present a strategy for identifying and correcting for aberration effects in Spherical Neutron Polarimetry. The transformation of the neutron beam polarization vector due to scattering from a material is determined with Spherical Neutron Polarimetry

Extreme Magnetic Field-Boosted Superconductivity

December 1, 2019
Author(s)
Sheng NMN Ran, I Lin NMN Liu, Yun Suk Eo, Daniel J. Campbell, Paul M. Neves, Wesley T. Fuhrman, Shanta Ranjan Saha, Christoper Eckberg, Hyunsoo Kim, David Graf, Fedor Balakirev, John Singleton, Johnpierre N. Paglione, Nicholas Butch
Applied magnetic fields underlie exotic quantum states, such as the fractional quantum Hall effect 1 and Bose-Einstein condensation of spin excitations 2. Superconductivity, on the other hand, is inherently antagonistic towards magnetic fields. Only in

On Low-Energy Tail Distortions in the Detector Response Function of X-Ray Microcalorimeter Spectrometers

November 21, 2019
Author(s)
Galen C. O'Neil, Paul Szypryt, Endre Takacs, Joseph N. Tan, Sean W. Buechele, Aung Naing, Young I. Joe, Daniel S. Swetz, Daniel R. Schmidt, William B. Doriese, Johnathon D. Gard, Carl D. Reintsema, Joel N. Ullom, John S. Villarrubia, Yuri Ralchenko
We use narrow spectral lines from the X-ray spectra of various highly charged ions to measure low-energy tail-like deviations from a Gaussian response function in a microcalorimeter X-ray spectrometer with Au absorbers at energies from 650 to 3320 eV. We

Chalcogenide Topological Insulators

November 15, 2019
Author(s)
Joseph A. Hagmann
The purpose of this chapter is to introduce the reader to the chalcogenide materials systems that host the topological insulator phase of quantum matter. Specifically, the HgTe quantum well 2D topological insulator system and the V2VI3-type bismuth- and

Correlating Decoherence in Transmon Qubits: Low Frequency Noise by Single Fluctuators

November 8, 2019
Author(s)
Steffen Schlor, Jurgen Lisenfeld, Clemens Muller, Alexander Bilmes, Andre Schneider, David P. Pappas, Alexey V. Ustinov, Martin Weides
We report on long-term measurements of a highly coherent, nontunable superconducting transmon qubit, revealing low-frequency burst noise in coherence times and qubit transition frequency. We achieve this through a simultaneous measurement of the qubit's

Flow Resistance & Structures in Viscoelastic Channel Flows at Low Re

November 5, 2019
Author(s)
Boyang Qin, Paul Salipante, Steven Hudson, Paulo E. Arratia
The flow of viscoelastic fluids in channels and pipes remain poorly understood, particularly at low Reynolds numbers. Here, we investigate the flow of polymeric solutions in straight channels using pressure measurements and particle tracking. The law of

Magnetic Ground State and Magnetic Excitations in Black Dioptase Cu 6 Si 6 O 18

November 1, 2019
Author(s)
A. Podlesnyak, O. Prokhnenko, S. E. Nikitin, A. I. Kolesnikov, M. Matsuda, Sachith E. Dissanayake, Timothy R Prisk, H. Nojiri, I. F. Diaz-Ortega, L. M. Anovitz
The low-temperature magnetic properties and magnetic structure of fully dehydrated black dioptase Cu 6Si 6O 18 have been studied by single-crystal neutron diffraction and magnetization measurements in magnetic fields up to 30 T. The intrachain J c and

Coexistence of Ferromagnetic Fluctuations and Superconductivity in the Actinide Superconductor UTe 2

October 23, 2019
Author(s)
Shyam Sundar, S. Gheidi, K. Akintola, A. M. Cote, S. R. Dunsiger, S. Ran, Nicholas Butch, S. R. Saha, J. Paglione, J. E. Sonier
We report low-temperature muon spin relaxation/rotation (υSR) measurements on single crystals of the actinide superconductor UTe 2. Below 5 K we observe a continuous slowing down of magnetic fluctuations, which persists through the superconducting

Spin Seebeck Imaging of Spin-Torque Switching in Antiferromagnetic Pt/NiO Heterostructures

October 22, 2019
Author(s)
Isaiah Gray, Takahiro Moriyama, Nikhil Sivadas, Gregory M. Stiehl, John T. Heron, Ryan F. Need, Brian Kirby, David H. Low, Katja Nowack, Darrell G. Schlom, Daniel C. Ralph, Teruo Ono, Gregory D. Fuchs
We demonstrate the spin Seebeck microscope as a sensitive method for imaging in-plane antiferromagnetic order in thin films. Recently, antidamping spin-orbit torques have been used to reorient Neel order in antiferromagnetic devices. Although the readout
