This article reviews recent developments in tests of fundamental physics using atoms and
molecules, including the subjects of parity violation, searches for permanent electric dipole …

Recent developments in frequency metrology and optical clocks have been based on
electronic transitions in atoms and singly charged ions as references. The control over all …

The current status of bound state quantum electrodynamics calculations of transition
energies for few-electron ions is reviewed. Evaluation of one and two body QED correction …

The research progresses on the investigations of atomic structure and collision dynamics
with highly charged ions based on the heavy ion storage rings and electron ion beam traps …

Highly charged ions play a crucial role in magnetic fusion plasmas. These plasmas are
excellent sources for producing highly charged ions and copious amounts of radiation for …

The present status of tests of QED with highly charged ions is reviewed. The theoretical
predictions for the Lamb shift and the transition energies are compared with available …

We performed a reference-free measurement of the transition energies of the 1 s 2 p 1 P 1→
1 s 2 1 S 0 line in He-like argon, and of the 1 s 2 s 2 2 p 1 P 1→ 1 s 2 2 s 2 1 S 0 line in Be …

We show that one may interpret physical reality as random fields in space-time. These have
a probability given by the expectation of a coherent state projection operator, called the Q …

We study various properties of the 2 p P 1/2 2− 2 p P 3/2 2 fine-structure splittings in the
boronlike S 11+, Cl 12+, Ar 13+, and K 14+ ions and the 4 p P 1/2 2− 4 p P 3/2 2 fine …

For the hydrogenlike Ar 17+ ion, the 1 s Lamb shift was absolutely determined with a 1.4%
accuracy based on Lyman-α wavelength measurements that have negligible uncertainties …
