We monitor the correlated quench induced dynamical dressing of a spinor impurity repulsively interacting with a Bose-Einstein condensate. Inspecting the temporal evolution of the structure factor, three distinct dynamical regions arise upon increasing the interspecies interaction. These regions are found to be related to the segregated nature of the impurity and to the Ohmic character of the bath.

- The study extends a method called Multi-Layer Multi-Configuration Time-Dependent Hartree (ML-MCTDH) for simulating the dynamics of bosonic mixtures to also include fermionic mixtures, creating a unified approach for indistinguishable particle mixtures.
- The new method, ML-MCTDHX, uses a multi-layer wave-function expansion to efficiently analyze both intra- and inter-species correlations in these mixtures.
- The effectiveness of ML-MCTDHX is demonstrated through its application to colliding few-atom mixtures, revealing that correlations significantly influence the outcomes of collisional events, particularly affecting reflection and transmission properties.
