Perfect revivals of Rabi oscillations and hybrid Bell states in a trapped ion
We show that perfect revivals of Rabi oscillations are possible, under certain conditions, in the population inversion of a trapped ion. Based on this property, we find that Schrödinger cat states of the atomic motion are naturally generated by the uni…

Entanglement-driven energy exchange in a two-qubit quantum battery
This study investigates the dynamics of quantum batteries (QBs), focusing on the pivotal role of quantum entanglement in mediating inter-cellular energy transfer within a two-cell configuration (two-qubit), wherein one cell is directly coupled to the c…

Calculations of positron scattering and annihilation from H-like ions
The single-center convergent close-coupling method is utilized to calculate positron scattering from H-like ions from He+ to F8+. Results for the normalized annihilation rate ( ) and the electron-loss, elastic, and bound-state excitation cross sections…

Phase diagram and elementary excitations of strongly interacting droplets with non-local interactions
A one-dimensional bosonic gas with strong contact repulsion and attractive non-local interactions may form a quantum droplet with a flat-top density profile. We focus on a system in the Tonks–Girardeau limit of infinitely strong contact repulsion. We s…

Ion momentum mapping in photodissociation and Coulomb explosion events using ion time-of-flight analyzers
Modern light sources such as free electron lasers allow tracking photoinduced events with unprecedented accuracy. Ion spectroscopy is a particularly useful tool, revealing for example momentum correlations in dissociation and Coulomb explosion patterns…
