Observation of anomalous tunneling in collective excitations via a cloud experiment platform for Bose-Einstein condensates
Daichi Kagamihara, Hironori Kazuta, Yewei Wu +2
Recent development of cloud-based experiment platforms has enabled physicists to examine theoretical concepts with unprecedented accessibility. Oqtant is a cloud-accessible platfor…
Slow molecular beams from a cryogenic buffer gas source
A. D. White, S. Popa, J. Mellado-Munoz +4
We study the properties of a cryogenic buffer gas source that uses a low temperature two-stage buffer gas cell to produce very slow beams of ytterbium monofluoride molecules. The m…
Measuring the stability of fundamental constants with a network of clocks
G. Barontini, L. Blackburn, V. Boyer +41
The detection of variations of fundamental constants of the Standard Model would provide us with compelling evidence of new physics, and could lift the veil on the nature of dark m…
