Prognostics and Health Management to Improve Resilient Manufacturing

October 23, 2020
Author(s)
Michael P. Brundage, Brian A. Weiss
Manufacturers need to be resilient to effectively mitigate substantial disruptions to manufacturing operations so they may remain competitive. Disruptions resulting from the COVID-19 global pandemic have caused manufacturers to experience new challenges

Quadruply-ionized barium as a candidate for a high-accuracy optical clock

October 23, 2020
Author(s)
Kyle Beloy, Vladimir A. Dzuba, Samuel Brewer
We identify Ba$^4+}$ (Te-like) as a promising candidate for a high-accuracy optical clock. The lowest-lying electronic states are part of a $^3P_J$ fine structure manifold with anomalous energy ordering, being non-monotonic in $J$. We propose a clock based
