Abstract

We Monitor The Correlated Quench Induced Dynamical Dressing Of A Spinor Impurity Repulsively Interacting With A Bose-Einstein Condensate. Inspecting The Temporal Evolution Of The Structure Factor, Three Distinct Dynamical Regions Arise Upon Increasing The Interspecies Interaction. These Regions Are Found To Be Related To The Segregated Nature Of The Impurity And To The Ohmic Character Of The Bath. It Is Shown That The Impurity Dynamics Can Be Described By An Effective Potential That Deforms From A Harmonic To A Double-Well One When Crossing The Miscibility-Immiscibility Threshold. In Particular, For Miscible Components The Polaron Formation Is Imprinted On The Spectral Response Of The System. We Further Illustrate That For Increasing Interaction An Orthogonality Catastrophe Occurs And The Polaron Picture Breaks Down. Then A Dissipative Motion Of The Impurity Takes Place Leading To A Transfer Of Energy To Its Environment. This Process Signals The Presence Of Entanglement In The Many-Body System.
