Pr10+ as a candidate for a high-accuracy optical clock for tests of fundamental physics
S. G. Porsev, C. Cheung, M. S. Safronova +4
The authors propose the In-like ion Pr10+ as a high‑accuracy optical clock candidate with strong sensitivity to variations of the fine‑structure constant, and they compute its low‑…
Portal for High-Precision Atomic Data and Computation
Amani Kiruga, Charles Cheung, Dmytro Filin +6
We've developed a scalable and sustainable online atomic data portal with an automated interface for easy update and addition of new data. The current portal provides energies, tra…
Polarizabilities of low-lying states of silver
S. G. Porsev, D. Filin, C. Cheung +1
Assembly of ultracold polar molecules containing silver (Ag) from laser-cooled atoms requires knowledge of the dynamic polarizabilities of Ag at convenient laser wavelengths. We pr…
A neural-network-based Python package for performing large-scale atomic CI using pCI and other high-performance atomic codes
Pavlo Bilous, Charles Cheung, Marianna Safronova
Modern atomic physics applications in science and technology pose ever higher demands on the precision of computations of properties of atoms and ions. Especially challenging is th…
pCI: a parallel configuration interaction software package for high-precision atomic structure calculations
Charles Cheung, Mikhail G. Kozlov, Sergey G. Porsev +3
We introduce the pCI software package for high-precision atomic structure calculations. The standard method of calculation is based on the configuration interaction (CI) method to…
High-Precision Transition Energy Measurements of Neon-like Fe XVII Ions
Chintan Shah, Moto Togawa, Marc Botz +15
We improve by a factor of 4-20 the energy accuracy of the strongest soft X-ray transitions of Fe XVII ions by resonantly exciting them in an electron beam ion trap with a monochrom…
