State-Insensitive Trapping of Alkaline-Earth Atoms in a Nanofiber-Based Optical Dipole Trap
K. Ton, G. Kestler, D. Filin +7
Neutral atoms trapped in the evanescent optical potentials of nanotapered optical fibers are a promising platform for developing quantum technologies and exploring fundamental scie…
Prospects of a thousand-ion Sn Coulomb-crystal clock with sub- inaccuracy
David R. Leibrandt, Sergey G. Porsev, Charles Cheung +1
We propose a many-ion optical atomic clock based on three-dimensional Coulomb crystals of order one thousand Sn ions confined in a linear RF Paul trap. Sn has a uniqu…
Calculation of energies and hyperfine structure constants of 233U^+ and 233U
S. G. Porsev, C. Cheung, M. S. Safronova
We carried out calculations of the energies and magnetic dipole hyperfine structure constants of the low-lying states of 233U^+ and 233U using two different approaches. With six va…
New Measurement Resolves Key Astrophysical Fe XVII Oscillator Strength Problem
Steffen Kühn, Charles Cheung, Natalia S. Oreshkina +19
One of the most enduring and intensively studied problems of X-ray astronomy is the disagreement of state-of-the art theory and observations for the intensity ratio of two Fe XVII…
