“…In other words, the many-body bound state becomes a trap state since the atoms are linked to the trapped ion. This observation aligns with our previous study on trap-induced atom-ion complexes 23 , where we show that the trap properties affect the lifetime of atom-ion complexes, as well as chemical processes relying on those complexes, such as three-body recombination.…”

“…Similarly, in previous efforts, the role of the ion trap has never been included, even though most of the promising experimental platforms count on a tight ion trap. Along these lines, we have recently found that it is indeed possible to readily control the reactivity of the ion via the properties of the trap parameters 23 . Therefore, the role of the trap on ion solvation in dilute quantum gases requires attention.…”

Solvation, the result of the complicated interplay between solvent-solute and solvent-internal interactions, is one of the most important chemical processes. Consequently, a complete theoretical understanding of solvation seems a heroic task. However, it is possible to elucidate fundamental solvation mechanisms by looking into simpler systems, such as ion solvation in atomic baths. In this work, we study ion solvation by calculating the ground state properties of a single ion in a neutral bath from the high-density regime to the low-density regime, finding common ground for these two, in principle, disparate regimes. Our results indicate that a single $^{174}$Yb$^+$ ion in a bath of $^{7}$Li atoms forms a coordination complex at high densities with a coordination number of 8, with strong electrostriction, characteristic of the snowball effect. On the contrary, treating the atomic bath as a dilute quantum gas at low densities, we find that the short range of the ion-atom interaction plays a significant role in the physics of many-body bound states and polarons. Furthermore, in this regime, we explore the role of a putative ion trap, which drastically affects the binding mechanism of the ion and atoms from a quantum gas. Therefore, our results give a novel insight into the universality of ion-neutral systems in the ultracold regime and the possibilities of observing exotic many-body effects.

The same is expected in the case of a Paul trap, based on the results for trap-assisted atom-ion complexes, where the trap increases the efficiency of forming and the lifetime of atom-ion complexes.…”

Solvation, the result of the complicated interplay between solvent–solute and solvent–internal interactions, is one of the most important chemical processes. Consequently, a complete theoretical understanding of solvation seems like a heroic task. However, it is possible to elucidate fundamental solvation mechanisms by looking into simpler systems, such as ion solvation in atomic baths. In this work, we study ion solvation by calculating the ground state properties of a single ion in a neutral bath from the high‐density to the low‐density regimes, finding common ground for these two, in principle, disparate regimes. Our results indicate that a single 174Yb+ ion in a bath of 7Li atoms forms a coordination complex at high densities with a coordination number of 8, with strong electrostriction characteristic of the snowball effect. On the contrary, treating the atomic bath as a dilute quantum gas at low densities, we find that the ion‐atom interaction's short‐range plays a significant role in the physics of many‐body‐bound states and polarons. Furthermore, in this regime, we explore the role of an ion trap necessary to experimentally realize this system, which drastically affects the binding mechanism of the ion and atoms from a quantum gas. Therefore, our results give a novel insight into the universality of ion‐neutral systems in the ultracold regime and the possibilities of observing exotic many‐body effects.Keypoints A global study of ion solvation in atomic baths from the high‐ to the low‐density regimes. The ion–atom short‐range interaction is critical to understanding the presence of many‐body‐bound states and polarons. The ion‐trapping potential drastically impacts many‐body‐bound states and polaron formation.
