Abstract
We Explore The Time Evolution Of Two Impurities In A Trapped One-Dimensional Bose Gas That Follows A Change Of The Boson-Impurity Interaction. We Study The Induced Impurity-Impurity Interactions And Their Effect On The Quench Dynamics. In Particular, We Report On The Size Of The Impurity Cloud, The Impurity-Impurity Entanglement, And The Impurity-Impurity Correlation Function. The Presented Numerical Simulations Are Based Upon The Variational Multilayer Multiconfiguration Time-Dependent Hartree Method For Bosons. To Analyze And Quantify Induced Impurity-Impurity Correlations, We Employ An Effective Two-Body Hamiltonian With A Contact Interaction. We Show That The Effective Model Consistent With The Mean-Field Attraction Of Two Heavy Impurities Explains Qualitatively Our Results For Weak Interactions. Our Findings Suggest That The Quench Dynamics In Cold-Atom Systems Can Be A Tool For Studying Impurity-Impurity Correlations.
