Impurity physics is a celebrated sub-discipline in condensed matter. Spectral study of impurity dynamics in atomic quantum Bose and Fermi gases has invigorated this line of research. Here, I will take baby steps toward understanding how Rydberg excitations in such gases probe the quantum correlation; few-body bound states and quantum statistics, how oligomeric Rydberg molecules evolve to many-body dressed states and how Fermi statistics block some of these pathways. I will also touch upon when impurity excitations are no longer isotropic.
