Challenges to miniaturizing cold atom technology for deployable vacuum metrology
Stephen Eckel, Daniel S. Barker, James A. Fedchak +3
Cold atoms are excellent metrological tools; they currently realize SI time and, soon, SI pressure in the ultra-high (UHV) and extreme high vacuum (XHV) regimes. The development of…
Fractal Universality in Near-Threshold Magnetic Lanthanide Dimers
Constantinos Makrides, Ming Li, Eite Tiesinga +1
Ergodic quantum systems are often quite alike, whereas nonergodic, fractal systems are unique and display characteristic properties. We explore one of these fractal systems, weakly…
Development of a new UHV/XHV pressure standard (cold atom vacuum standard)
Julia Scherschligt, James A Fedchak, Daniel S Barker +4
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, covering a pressure range…
