Audrey N. Tong, Lukasz L. Diduch, Jonathan G. Fiscus, Yasaman Haghpanah, Shudong Huang, David M. Joy, Kay Peterson, Ian M. Soboroff
Initiated in conjunction with DARPA's Low Resource Languages for Emergent Incidents (LORELEI) Program, the NIST LoReHLT (Low Re-source Human Language Technology

Spontaneous avalanche dephasing in large Rydberg ensembles

Author(s)
Thomas L. Boulier, Eric Magnan, Carlos Bracamontes, James Maslek, Elizabeth Goldschmidt, Jeremey Young, Alexey Gorshkov, Steven Rolston, James V. Porto
Strong dipole-exchange interactions due to spontaneously produced contaminant states can trigger rapid dephasing in many-body Rydberg ensembles [E. Goldschmidt

Valley blockade in a silicon double quantum dot

Author(s)
Justin K. Perron, Michael Gullans, Jacob Taylor, Michael Stewart, Neil M. Zimmerman
Electrical transport in double quantum dots (DQD) is useful for illuminating many interesting aspects of the carrier states in quantum dots. Here we show data

Development of a new UHV/XHV pressure standard (Cold Atom Vacuum Standard)

Author(s)
Julia Scherschligt, James A. Fedchak, Daniel Barker, Stephen Eckel, Nikolai Klimov, Constantinos Makrides, Eite Tiesinga
The National Institute of Standards and Technology has recently begun a program to develop a primary pressure standard that is based on ultra-cold atoms

Resonant X-ray Emission of Hexagonal Boron Nitride

Author(s)
John T. Vinson, Terrence J Jach, Matthias Mueller, Rainer Unterumsberger, Burkhard Beckhoff
The electronic structure of hexagonal boron nitride ({\it h}-BN) is explored using measurements of x-ray absorption and resonant inelastic x-ray scattering

Results of an International Comparison of Activity Measurements of 68Ge

Author(s)
Jeffrey T. Cessna, Ryan P. Fitzgerald, Brian E. Zimmerman, Lizbeth Laureano-Perez, Denis E. Bergeron
An international key comparison, identifier CCRI(II)-K2.Ge-68, has been performed. The National Institute of Standards and Technology (NIST) served as the pilot

Flux-tunable phase shifter for microwaves

Author(s)
Roope J. Kokkoniemi, Tuomas Ollikainen, Sakari Saarenpaa, Janne Kokkala, Ceren Dag, Mikko Mottonen, Russell Lake
We introduce a magnetic-flux-tunable phase shifter for propagating microwave photons, based on three equidistant superconducting quantum interference devices

Quantum Estimation of the Classical Gravitational Field

Author(s)
Emanuel H. Knill, T. G. Downes, G. J. Milburn, C. M. Caves, J. R. van Meter
Here we describe a quantum limit to measurement of the classical gravitational field. Specifically, we formulate the quantum Cramer-Rao lower bound for

Deriving global OH abundance and atmospheric lifetimes for long-lived gases: A search for the alternative reference gas for CH3CCl3.

Author(s)
Qing Liang, Martyn P. Chipperfield, Eric L. Fleming, Luke Abraham, Peter Braesicke, James B. Burkholder, John S. Daniels, Sandip Dhomse, Steven C. Hardiman, Charles H. Jackman, Douglas E. Kinnison, Stephen A. Montzka, Olaf Morgenstern, Archie McCulloch, Paul A. Newman, Vladimir L. Orkin, Giovanni Pitari, Matthew Rigby, Eugene Rozanov, Fiona Tummon, Guus J. Velders, Daniele Visioni
An accurate estimate of global hydroxyl radical (OH) abundance is important for projections of air quality, climate, and stratospheric ozone layer recovery. As
