Query: Ionic polaron in a Bose-Einstein condensate   The presence of strong interactions in a many-body quantum system can lead to
a variety of exotic effects. Here we show that even in a comparatively simple
setup consisting of a charged impurity in a weakly interacting bosonic medium
the competition of length scales gives rise to a highly correlated mesoscopic
state. Using quantum Monte Carlo simulations, we unravel its vastly different
polaronic properties compared to neutral quantum impurities. Moreover, we
identify a transition between the regime amenable to conventional perturbative
treatment in the limit of weak atom-ion interactions and a many-body bound
state with vanishing quasi-particle residue composed of hundreds of atoms. In
order to analyze the structure of the corresponding states we examine the
atom-ion and atom-atom correlation functions which both show nontrivial
properties. Our findings are directly relevant to experiments using hybrid
atom-ion setups that have recently attained the ultracold regime.
