Query: Dynamical excitation processes and correlations of three-body
  two-dimensional mixtures   A scheme is proposed to dynamically excite distinct eigenstate superpositions
in three-body Bose-Fermi mixtures confined in a two-dimensional harmonic trap.
The system is initialized in a non-interacting state with a variable spatial
extent, and the scattering lengths are subsequently quenched. For spatial
widths smaller than the three-body harmonic oscillator length, a superposition
of trimers and atom-dimers is dynamically attained, otherwise trap states are
predominantly populated. Accordingly, the Tan contacts evince the build-up of
short range two- and three-body correlations in the course of the evolution. A
larger spatial extent of the initial state leads to a reduction of few-body
correlations, endowed however with characteristic peaks at the positions of the
avoided-crossings in the energy spectra, thereby signalling the participation
of atom-dimers. Our results expose ways to dynamically excite selectively
trimers, atom-dimers and trapped few-body states characterized by substantial
correlations and likely to be accessible within current experiments.
