Schmelcher author MiLe department ISTplus - Postdoctoral Fellowships project 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. https://research-explorer.ista.ac.at/download/7919/7926/2020_PhysRevResearch_Mistakidis.pdf application/pdfno American Physical Society2020 eng 2643-156410.1103/physrevresearch.2.023154 2 Mistakidis, S.
