Explicitly correlated wave function for a boron atom
Mariusz Puchalski, Jacek Komasa, Krzysztof Pachucki
We present results of high-precision calculations for a boron atom's properties using wave functions expanded in the explicitly correlated Gaussian basis. We demonstrate that the w…
Precision Test of Many-Body QED in the Be Fine Structure Doublet Using Short-Lived Isotopes
Wilfried Nörtershäuser, Christopher Geppert, Andreas Krieger +13
Absolute transition frequencies of the transitions in Be were measured for the isotopes Be. The fine st…
Quantum electrodynamics and corrections to the fine splitting in Li and Be
Mariusz Puchalski, Krzysztof Pachucki
We derive quantum electrodynamics corrections to the fine structure in three-electron atomic systems at and orders and present their numerical evaluations for…
Frequency-dependent polarizability of helium including relativistic effects with nuclear recoil terms
Konrad Piszczatowski, Mariusz Puchalski, Jacek Komasa +2
Future metrology standards will be partly based on physical quantities computed from first principles rather than measured. In particular, a new pressure standard can be establishe…
