Resource-efficient dissipative entanglement of two trapped-ion qubits

August 6, 2021
Daniel Cole, Stephen Erickson, Giorgio Zarantonello, Panyu Hou, Jenny Wu, Karl Horn, Daniel Slichter, Florentin Reiter, Christiane Koch, Dietrich Leibfried
We demonstrate a simplified method for generating an entangled state of two trapped-ion qubits. Our implementation produces its target state faster and with higher fidelity than previous demonstrations of dissipative entanglement generation, while

A System for Validating Resistive Neural Network Prototypes

July 27, 2021
Brian Hoskins, Mitchell Fream, Matthew Daniels, Jonathan Goodwill, Advait Madhavan, Jabez J. McClelland, Osama Yousuf, Gina C. Adam, Wen Ma, Muqing Liu, Rasmus Madsen, Martin Lueker-Boden
Building prototypes of heterogeneous hardware systems based on emerging electronic, magnetic, and photonic devices is an increasingly important area of research. On the face of it, the novel implementation of these systems, especially for online learning

Programmable System on Chip for controlling an atomic physics experiment

July 23, 2021
Ananya Sitaram, Gretchen K. Campbell, Alessandro Restelli
Most atomic physics experiments are controlled by a digital pattern generator used to synchronize all equipment by providing triggers and clocks. Recently, the availability of well-documented open-source development tools has lifted the barriers to using

The role of orientation in the MEL response of OLEDs

July 13, 2021
Sebastian Engmann, Emily Bittle, Lee J. Richter, Rawad Hallani, John Anthony, David J. Gundlach
Magneto electroluminescence (MEL) is emerging as a powerful tool for the study of spin dynamics in emitting devices. The shape of the MEL response is typically used to draw qualitative inference on the dominant process (singlet fission or triplet fusion)

Broadband stability of the Habitable Zone Planet Finder Fabry-Perot etalon calibration system:evidence for chromatic variation

July 8, 2021
Ryan C. Terrien, Joe P. Ninan, Scott Diddams, Suvrath Mahadevan, Samuel Halverson, Chad Bender, Connor Fredrick, Fred Hearty, Jeffrey M. Jennings, Andrew J. Metcalf, Andrew J. Monson, Arpita Roy, Christian Schwab, Gudmundur Stefansson
The comb-like spectrum of a white light-illuminated Fabry-Pérot etalon can serve as a cost-effective and stable reference source for precise Doppler measurements. Understanding the stability of these devices across their broad (100's of nm) spectral

CODATA Recommended Values of the Fundamental Physical Constants: 2018

June 30, 2021
Eite Tiesinga, Peter Mohr, David B. Newell, Barry Taylor
We report the 2018 self-consistent values of constants and conversion factors of physics and chemistry recommended by the Committee on Data of the Interna- tional Science Council (CODATA). The recommended values can also be found at

IRIS-HEP Blueprint Workshop Summary: Learning from the Pandemic: the Future of Meetings in HEP and Beyond

June 30, 2021
Mark Neubauer, Todd Adams, Jennifer Adelman-McCarthy, Gabriele Benelli, Tulika Bose, David Britton, Ben Galewsky, Bo Jayatilaka, Brendan Kiburg, Maciej Gladki, Aman Goel, Jonathan E. Guyer, Pat Burchat, Joel Butler, Timothy Cartwright, Tomas Davidek, Jacques Dumarchez, Peter Elmer, Matthew Feickert, Mandeep Gill, Benjamin Krikler, David Lange, Claire Lee, Nick Manganelli, Giovanni Marchiori, Meenakshi Narain, Ianna Osborne, Jim Pivarski, Harrison Prosper, Graeme Stewart, Eduardo Rodrigues, Roberto Salerno, Marguerite Tonjes, Jaroslav Trnka, Vera Varanda, Vassil Vassilev, Gordon Watts, Sam Zeller, Yuanyuan Zhang
The COVID-19 pandemic has by-and-large prevented in-person meetings since March 2020. While the increasing deployment of effective vaccines around the world is a very positive development, the timeline and pathway to "normality" is uncertain and the "new

Role of low molecular weight polymers on the dynamics of silicon anodes during casting

May 11, 2021
Mary Burdette, Beth Armstrong, Ryan Murphy, Luke Heroux, Mathieu Doucet, Stephen Trask, Alexander Rogers, Gabriel Veith
This work probes the slurry architecture of a high silicon content electrode slurry with and without low molecular weight polymeric dispersants as a function of shear rate to mimic electrode casting conditions for poly(acrylic acid) (PAA) and lithium

Quantum field theory for the chiral clock transition in one spatial dimension

May 3, 2021
Seth P. Whitsitt, Rhine Samajdar, Subir Sachdev
We describe the quantum phase transition in the N-state chiral clock model in spatial dimension d=1. With couplings chosen to preserve time-reversal and spatial inversion symmetries, such a model, is in the universality class of recent experimental studies

Identifications of extreme ultraviolet spectra of Br-like to Ni-like neodymium ions using an electronbeam ion trap

April 30, 2021
C. Suzuki, Dipti Goyal, Y. Yang, A. Gall, Roshani Silwal, S. Sanders, Aung S. Naing, Joseph N. Tan, Endre A. Takacs, Yuri Ralchenko
Charge-resolved extreme ultraviolet spectra of open N-shell neodymium (Nd) ions have been recorded in an electron beam ion trap facility at the National Institute of Standards and Technology. The measurements have been performed for nominal electron beam

Spontaneous Pulse Formation in Edgeless Photonic Crystal Resonators

April 29, 2021
Su P. Yu, Daniel Cole, Hojoong Jung, Gregory Moille, Kartik Srinivasan, Scott Papp
Complex systems are a proving ground for fundamental interactions between components and their collective emergent phenomena. Through intricate design, integrated photonics offers intriguing nonlinear inter- actions that create new patterns of light. In

Neutron Spin Rotation Measurements

Jeffrey S. Nico, Shannon M. Hoogerheide, Hans Pieter Mumm, Murad Sarsour, J Amadio, Eamon Anderson, Libertad Barron-Palos, Bret Crawford, Chris Crawford, D. Esposito, Walter Fox, I Francis, J Fry, Chris Haddock, Adam Holley, Kirill Korsak, J Lieers, S Magers, M. Maldonado-Velazquez, D Mayorov, T Okudaira, C Paudel, S Santra, H.M. Shimizu, William M. Snow, A. Sprow, K. Steen, H E. Swanson, John Vanderwerp, P. A. Yergeau
The neutron spin rotation (NSR) collaboration used parity-violating spin rotation of transversely polarized neutrons transmitted through a 0.5 m liquid helium target to constrain weak coupling constants between nucleons. While consistent with theoretical
