Abstract

We Unravel The Periodically Driven Dynamics Of Two Repulsively Interacting Bosonic Impurities Within A Bosonic Bath Upon Considering Either The Impact Of A Finite Pulse Or Continuous Shaking Of The Impurities Harmonic Trap. Following A Pulse Driving Of Initially Miscible Components, We Reveal A Variety Of Dynamical Response Regimes Depending On The Driving Frequency. At Resonant Drivings, The Impurities Decouple From Their Host, While If Exposed To A High-Frequency Driving, They Remain Trapped In The Bosonic Gas. For Continuous Shaking, We Showcase That In The Resonantly Driven Regime The Impurities Oscillate Back And Forth Within And Outside The Bosonic Medium. In All Cases, The Bosonic Bath Is Perturbed Performing A Collective Dipole Motion. Referring To An Immiscible Initial State, We Unveil That For Moderate Driving Frequencies The Impurities Feature A Dispersive Behavior While For A High-Frequency Driving They Oscillate Around The Edges Of The Thomas-Fermi Background. Energy Transfer Processes From The Impurities To Their Environment Are Encountered, Especially For Large Driving Frequencies. Additionally, Coherence Losses Develop In The Course Of The Evolution With The Impurities Predominantly Moving As A Pair.
