“…In these experiments, either lasercooled and trapped ions are immersed into ultracold trapped clouds of neutral atoms, or ions are directly produced within an ultracold parent gas (for reviews, see, e.g., [15,16]). Typical setups allow for a high level of control over the collision energy between the atom and the ion, for which values around 1 mK × k B and below have been achieved [46][47][48][49]. We note that in Paul traps, electric fields are used to confine ions.…”

“…The study of interactions between neutral atoms and ions is a highly topical and promising area of research at the intersection of several disciplines including atomic physics, chemistry and quantum simulations [1][2][3][4][5][6][7][8][9][10][11][12]. Many current experiments exploit combinations of established trapping methods, building on the concept of ion-atom hybrid traps first demonstrated by Smith et al in 2005 [1], and have revealed interesting effects and phenomena such as sympathetic cooling [4,5,8,9,11,[13][14][15][16][17][18], state-to-state chemistry [19], non-Maxwellian and superstatistical energy distributions [20,21], charge exchange and transfer [22,23], and ion-atom Feshbach resonances [18]. Despite this rapid progress, one of the problems encountered in most experiments suitable for studying generic combinations of ion and atom species is related to the fact that they employ radiofrequency (rf) fields to confine ions.…”

“…In the rapidly developing field, several promising approaches have been brought forward or demonstrated. For example, controlled Rydberg excitation can be used to achieve very low kinetic energies of ions positioned in an atomic cloud [22,25,26]. Another approach that was successfully applied to achieve sympathetic cooling close to the quantum regime makes use of the fact that the impact of heating depends on the atom-ion mass ratio and can be mitigated by immersing ions with a large mass, e.g., Yb + in a cloud of extremely light neutral atoms such as Li [15].…”

“…With the advent of experimental techniques enabling the control of cold ions immersed in ultracold neutral atoms [22][23][24][25][26][27][28][29], the study of weakly-bound neutral molecules can be extended to molecular ions. In this context, a new type of Rydberg molecule has been theoretically proposed, consisting of an ion and a Rydberg atom [30,31].…”
