The first measurements of the magnetic dipole hyperfine structure constants A in singly ionized thulium revealed substantial discrepancies with the corresponding theoretical calculations. Subsequent measurements expanded the very limited available da...

Inspired by the well-known experimental connections between $X\left(3872\right)$, $Z_{cs}\left(4220\right)$, and $Y\left(4620\right)$, we systematically study the recently reported strange partner of $T_{cc}$, the $1^{+}$$cc\overline{q}\overline{s}$ system, and its orbital excitation state $1^{-}$$cc\overline{q}\overline{s}$...

The potential energy curves and spectroscopic constants of the ground and several low-lying excited states of the Ca^q+-Kr (q = 0, 1, 2) van der Waals complexes were investigated using one- and two-electron pseudopotential approaches. This treatment e...

We present a general procedure to describe the dynamics of N degenerate quantized fields interacting resonantly with a two–level atom, all coupled with the same strength, within the rotating–wave approximation. Starting from the analysis...

We report experimental measurements of the absolute photoionization cross sections for chlorine ions in different stages of ionization, over photon energy ranges corresponding to the L-shell (2s and 2p subshells) excitations. Single, double and tripl...

We explore the physical quantum properties of atoms in fractal spaces, both as a theoretical generalization of normal integer-dimensional Euclidean spaces and as an experimentally realizable setting. We identify the threshold of fractality at which E...

We report on the realization of a platform for trapping and manipulating individual ⁸⁸Sr atoms in optical tweezers. A first cooling stage based on a blue shielded magneto-optical trap (MOT) operating on the ${|}^1{\mathrm{S}}_0⟩\to {|}^1{\mathrm{P}}_1⟩$ transition a...
