Abstract

We Unravel The Ground-State Properties And The Nonequilibrium Quantum Dynamics Of Two Bosonic Impurities Immersed In A One-Dimensional Fermionic Environment By Applying A Quench Of The Impurity-Medium Interaction Strength. In The Ground State, The Impurities And The Fermi Sea Are Phase Separated For Strong Impurity-Medium Repulsions While They Experience A Localization Tendency Around The Trap Center For Large Attractions. We Demonstrate The Presence Of Attractive Induced Interactions Mediated By The Host For Impurity-Medium Couplings Of Either Sign And Analyze The Competition Between Induced And Direct Interactions. A Quench To Repulsive Interactions Triggers A Breathing Motion In Both Components, With An Interaction Dependent Frequency And Amplitude For The Impurities, And A Dynamical Phase Separation Between The Impurities And Their Surrounding For Strong Repulsions. For Attractive Postquench Couplings A Beating Pattern Owing Its Existence To The Dominant Role Of Induced Interactions Takes Place With Both Components Showing A Localization Trend Around The Trap Center. In Both Quench Scenarios, Attractive Induced Correlations Are Manifested Between Noninteracting Impurities And Are Found To Dominate The Direct Ones Only For Quenches To Attractive Couplings.
