DOI: 10.1103/physreva.100.022701
Abstract: We report experimental studies of atom-ion collisions in the thermal regime (several hundred Kelvin) using trapped ytterbium (Yb$^+$) ions immersed in potassium (K) vapor. Various collisional rate coefficients of the Yb$^+$ ion per K-atom number… read more here.

DOI: 10.1103/physrevlett.129.153401
Abstract: We explore the interaction between two trapped ions mediated by a surrounding quantum degenerate Bose or Fermi gas. Using perturbation theory valid for weak atom-ion interaction, we show analytically that the interaction mediated by a… read more here.

DOI: 10.1103/physrevlett.130.143003
Abstract: We theoretically investigate the trap-assisted formation of complexes in atom-ion collisions and their impact on the stability of the trapped ion. The time-dependent potential of the Paul trap facilitates the formation of temporary complexes by… read more here.
