In this talk, various aspects of this theoretical concept will be discussed in the context of ultracold bosonic atoms:
First, I will
consider the decay of dark solitons due to dynamical quantum depletion
as an example for how a natural-orbital analysis can help unravelling
complex many-body processes and intriguing aspects of local
correlations. Secondly, it will be shown how two-body correlation
measurements can in turn be utilized for reconstructing the
natural-orbital densities for a certain class of many-body states.
Finally, I will discuss in the context of binary bosonic mixtures how
the interplay between inter-species correlations and excitation transfer
can be made transparent by applying the natural-orbital analysis
generalized to a whole species.
