Abstract

We Unravel The Polaronic Properties Of Impurities Immersed In A Correlated Trapped One-Dimensional Bose-Bose Mixture. This Setup Allows The Impurities To Couple Either Attractively Or Repulsively To A Specific Host, Thus Offering A Highly Flexible Platform For Steering The Emergent Polaronic Properties. Specifically, The Impurity Residue Peak And Strength Of Induced Interactions Can Be Controlled By Varying The Coupling Of The Impurities To The Individual Bosonic Components. In Particular, It Is Possible To Maintain The Quasiparticle Character For Larger Interaction Strengths As Compared To The Case Of Impurities Immersed In A Single Bosonic Species. We Explicate A Hierarchy Of The Polaron Binding Energies In Terms Of The Impurity-Medium Interactions, Thereby Elucidating The Identification Of The Polaronic Resonances In Recent Experimental Radio-Frequency Schemes. For Strong Attractive Impurity-Medium Couplings, Bipolaron Formation Is Captured. Our Findings Pave The Way For Continuously Changing The Quasiparticle Character, Under The Impact Of Trap Effects, While Exposing The Role Of Correlations In Triple-Mixture Settings.
