Ionic polaron in a Bose-Einstein condensate

An impurity introduced to a many-body quantum environment gets dressed by excitations and it is of a particular interest to understand the limits of the quasi-particle description. The authors theoretically and numerically study an ionic impurity immersed in a weakly interacting gas of bosonic atoms...
