Detection and manipulation of the transverse motion in a Stark decelerator

July 17, 2021
Author(s)
Piotr Wcislo, Hao Wu, David Reens, Alexander Aeppli, Jun Ye
By enabling precise control over longitudinal velocity, Stark deceleration has become an important tool for studying cold collisions. However, the information about transverse motion is often hard to extract and to some extent beyond control. Here we

Woolverton, M. Yeh, A. Zhang, C. Zhang, X. Zhang
If dark matter has mass lower than around 1 GeV, it will not impart enough energy to cause detectable nuclear recoils in many direct-detection experiments. However, if dark matter is upscattered to high energy by collisions with cosmic rays, it may be

The role of orientation in the MEL response of OLEDs

July 13, 2021
Author(s)
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
Author(s)
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

Dissipative preparation of W states in trapped ion systems

July 2, 2021
Author(s)
Daniel Cole, Jenny Wu, Stephen Erickson, Panyu Hou, Andrew C. Wilson, Dietrich Leibfried, Florentin Reiter
We present protocols for dissipative entanglement of three trapped-ion qubits, and we discuss in detail a scheme that uses sympathetic cooling as the dissipation mechanism. This scheme relies on tailored destructive interference to generate one of six

CODATA Recommended Values of the Fundamental Physical Constants: 2018

June 30, 2021
Author(s)
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 physics.nist.gov

Dipole-Dipole Frequency Shifts in Multilevel Atoms

June 30, 2021
Author(s)
Andre Cidrim, Asier Pineiro Orioli, Christian Sanner, Ross B. Hutson, Jun Ye, Romain Bachelard, Ana Maria Rey
Dipole-dipole interactions lead to frequency shifts which are expected to limit the performance of next generation atomic clocks. In this work, we compute dipolar frequency shifts accounting for the intrinsic atomic multilevel structure in standard Ramsey

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

June 30, 2021
Author(s)
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

Prospects of a Pb$^2+}$ ion clock

June 29, 2021
Author(s)
Kyle Beloy
We propose a high-performance atomic clock based on the 1.81 PHz transition between the ground and first-excited state of doubly ionized lead. Utilizing an even isotope of lead, both clock states have $I=J=F=0$, where $I$, $J$, and $F$ are the conventional
