Abstract

We Unravel The Correlated Tunneling Dynamics Of An Impurity Trapped In A Double Well And Interacting Repulsively With A Majority Species Of Lattice Trapped Bosons. Upon Quenching The Tilt Of The Double Well It Is Found That The Quench-Induced Tunneling Dynamics Depends Crucially On The Interspecies Interaction Strength And The Presence Of Entanglement Inherent In The System. In Particular, For Weak Couplings The Impurity Performs A Rather Irregular Tunneling Process In The Double Well. Increasing The Interspecies Coupling It Is Possible To Control The Response Of The Impurity Which Undergoes A Delayed Tunneling While The Majority Species Effectively Acts As A Material Barrier. For Very Strong Interspecies Interaction Strengths The Impurity Exhibits A Self-Trapping Behavior. We Showcase That A Similar Tunneling Dynamics Takes Place For Two Weakly Interacting Impurities And Identify Its Underlying Transport Mechanisms In Terms Of Pair And Single-Particle Tunneling Processes.
