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...

description	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 and demonstrate the existence of two main phases of a polaronic regime for weak interactions, and a strongly correlated state with many bosons bound to the ion.
