We argue that the canonical partition function derived by Eyube et al (2021 J. Phys. B 5 155102) is not correct because the authors did not take into account the contribution of the rotational degrees of freedom. Consequently, the thermodynamic functio…

We investigate the effects of an external random δ-correlated potential on the bulk properties of self-bound droplets in three-dimensional binary Bose–Einstein condensates. The ground-state energy and the quantum fluctuation induced by disorder are com…
We apply deep learning for retrieval of the time-dependent bond length in the dissociating two-dimensional H molecule using photoelectron momentum distributions. We consider a pump-probe scheme and calculate electron momentum distributions from strong-…
We study the three-photon ionization of atomic lithium by intense, short light pulses, via numerically solving the time-dependent Schrödinger equation. Two-photon Rabi oscillations are induced between the 2s and 4s states, which are damped due to singl…
We explore the dielectronic recombination structures at the electron beam ion trap at Jagiellonian University in Cracow, emited by cerium that is produced by the high-current cathode made of iridium and cerium. Small amounts of these elements evaporate…
The lack of reliable atomic data can be a severe limitation in astrophysical modelling, in particular of events such as kilonovae that require information on all neutron-capture elements across a wide range of ionization stages. Notably, the presence o…
We report on the measurements of magnetically assisted dispersion and gain in a Zeeman degenerate two-level system associated with the closed D2 hyperfine transition cold cesium atoms. We use a Mach–Zehnder interferometer to measure the dispersive prop…
Intra-configuration fine-structure transitions in highly charged ions (HCIs) result in most cases from changes in the coupling of equivalent electrons. They are multipole forbidden to varying degrees and often occur within the optical range. In HCI wit…
